Over the years I've learned to tag my initials onto the end of anything that is my own preset / macro / template etc. Then I can find my own "favorites" in any search window by just typing my initials. Not a "Favorites" feature per se, but it works in any app
Custom actions also float to the top of the window - if you just want your own frequently used Actions to be visible there, you could create a Custom action that just executes the command in question...?
