Automatically? As far as I know: no, only with plugins.
Manually: yes, you can. If you draw shapes on the copper layer, you may then convert them to fill zones or traces and associate with target nets. With arcs and holding Ctrl for snapping it’s not that hard to get what you want. But that is really tedious work. Unless you are being paid to do so, have a technical reason to use teardrops/filets or just preparing a show off board, I would avoid that option as much as possible.
