this feature would be great ! I share here my use case if it can help:

I created an action to avoid repeating some code. I kept it private, and used it like 10 times . Now that I configured these 10 steps, I realised I need to make some changes to the action. Is there a quick way to apply code changes to the 10 steps that use this action ? At the moment can only delete, recreate and reconfigure the step to use the new code 10 times, it’s kind of frustrating If I need to do that for every change/adjustment of the action I need to make.

This is now possible with the newest version of actions:

See the docs here and let us know if you have any additional feedback!
