I thought I saw there was a way a LONG time back but I just can't remember.  I want to be able to change what the default modules that show up in Pro channels, I'm tired of always replacing and deleting the ones I don't use or need on a regular bases.  Is there a way or am is my memory just failing me?

Add what you want, right click in PC and select (wording may be slightly different) Set current as track/bus default.

Set the modules you want in any Pro Channel module - right click in a blank  area and choose "Set Modules as Default  for Tracks"
 
Do the same for busses
