Hello to the whole forum,
I am designing some PCB boards and I would like to ask you some advice regarding the most correct method to perform the panelization with Altium.

In practice I would have 8 projects complete with different boards and I would like to make a single panel. I understand how to panel multiple boards of the same project, it is quite simple because the properties panel allows you to intuitively set the number of boards per row and column and the margins between each boards. On the other hand, as far as the tiling between different boards is concerned, I have not found a very effective method, if not that of positioning them manually and of distancing them approximately by measuring the distance between each one. This method does not seem to me very precise and effective, especially if corrections are to be made later. I would therefore like to ask if you know any more relevant techniques for doing this.

My boards also include special strings containing some parameters of the project and I would like to point out that from what I noticed they are correctly interpreted only if the respective projects are open at the same time, otherwise they are not converted.

Also some of my pcb make use of footprints that have some primitives (traces on silkscreen layer and mounting holes) that come out from the board outline. This isn't a big deal for me as the board size has already been calculated and all the relevant elements of the components are inside the board. However I would like to make sure that all the primitives that come out from the edge are discarded and that they do not create confusion for the producer who could misinterpret the actual size of the board. I don't want to modify the single footprint, because it is already correctly defined and I can use it later for other projects. Therefore, I would like to ask you which is the most correct method to do what I ask, specifying that the board border has been defined both as a board outline layer and as a keep-out layer.

The main problem I encountered when I created the panel with all the boards is that the primitives (traces on silkscreen layer and mounting holes) that come out of some boards are superimposed on other boards and this I would really like to avoid. I also noticed that some details are missing in the panel view which are then generated in the gerber files. That is, the dimensions of each individual board and the tables with the holes that I created for each board on the drill drawings layer are shown in the gerber of the complete panel, all superimposed on each other. I would like to avoid this thing if possible without modifying the design of the single board, however, because it must be in its own right and include only the dimensions and the table of the entire panel.

I attach some images that highlight the problem described.

I thank in advance all those who will give me a hand.
