Would be useful to sometimes use an already saved Action Group (AG) as the basis for a temporary set of actions that need only be performed once (and not saved, similar to a Quick Action (QA)).
QAs are good but you basically always have to start from scratch and they can't be a series of actions unlike AGs. Why not allow "Quick Action Groups": AGs that are based off pre-existing saved ones and can be a one-off? For example, if I've got an AG that replaces all instances of the word "Electronic" and then splits upon "," into multiple fields, I could edit it before running and change the first action's replace term to "Rock", hit run, and the rest of the AG's actions will be performed the same.
This'd be an improvement upon temporarily duplicating QAs, running them, and then deleting them (or leaving them be and slowly crowding up the list with slight variations of one another).
Perhaps "Quick Action Groups" wouldn't be the right name for this feature, though I wouldn't be against such a feature that behaved just like QAs but for AGs (starts blank, and you build it from scratch), but I'd find it much more useful to allow using my own AGs as starting templates to perform a "QAG".
