Morning, Grazie.
When you've set up you FXs and stuff for an audio track, save the FXs as a package. open the FX dialogue, click Save As etc. THEN, when you dump that package on another track, all FXS, settings and tweaks are preserved. So if you have a way with words (=a standard approach to dialogue tracks) just call your package dia1 and use it every time. It's still further tweakable, but you get a head start so to speak.

I'm afraid not.
The quickest I've seen (we are talking about TRACK FXs here, no?) is duplicate track A, delete all events on the dupe and move all events from track B to the track A dupe. Delete track B.
