I figured out a search to determine which tasks require a time estimate.
I add this with search operator ' tagContains:' to work just with my action tagged tasks. I prefix all my action tags with '0' such as 0errands, 0home, 0macbook, etc. Then my Actions to Add Time Estimates search is:
tagContains:"0" not timeEstimate:">0"
**Smart List bonus!** As I add time estimates the tasks are instantly removed from the Smart List and I can work down getting all those tasks upto date. Sweet!
Pro Tip: Use the shortcut key 'g' for editing time estimates fast!
