+1 for this issue, not sure how this was overlooked and not reported previously. I have multiple actions in my repositories and working with them is a nightmare.

@agracio I'm in the same situation. It's even used as an example to place them in the directory that I have. How is that not implemented as basic functionality in the plugin?
