Link separate action strips back to a single animation

So, I made a big animation with the NLA editor for the first time and I started duplicating action strips with SHIFT D instead of ALT D. Now I need to edit my actions but they are separate instead of linked. (like action, action.01, action.02)

Each action strip in the NLA is synced to a sound track and placed precisely so I don’t want to place them again. Is there a way I can link the strips back to a single action without removing the strips from the NLA?

Thank you!

You can select them all and press Ctrl+L to link, unless I’m mistaken
