Add a PSpice command to a schematic

[AJollet]

I'd like to know how to add raw PSpice commands to a design in OrCad Capture. So far I've done everything using the menus but that's quite limiting.
Editing the output file seems complicated and it will be overwritten each time I lauch a simulation anyway.
So how can I add let's say ".IC V(1) = 0" to my design ?
