semi-automated tools for thinning automation data

I spend a ton of time cleaning up spurious automation between audio regions.
Many times this is to smooth out instantaneous volume jumps at the start or end of a region. When automation is dense, manual selection is super tedious.
Two suggestions:
1) User selects 1 or more automation pts between two regions and a shortcut key can be invoked to "expand automation selection up to pre-post region boundaries". The "DEL" to clear them if it looks "safe" to do so.

2) Provide a "grow/Shrink" selected automation points hot key function. So that a user can pick a middle automation pt, and manually exand(or shrink)
the selected list of automation points by a point from each end per invocation.

This will help me leave just the points I want in case the automation value I want for a region happens to be defined outside that region.

3) Ability to select a whole track and "Create automation keys" at the region boundaries if there is no key present (+/- some delta of time).
