Apply a new Content Master slide and Theme to an existing course?

[AndOr26367]

I started learning CapClassic just throwing objects on a slide and playing around with interactivity. Of course I ended up with something I liked, so kept going. Ended up being the basis for a course I want to keep but of course I hadn't explored themes and Content Master slides back then (yes, I do things backwards/the hard way a lot). After learning about CMs I created one and want to apply it to the old course and would prefer a blank theme since it was all custom/manual content originally. Can I do this, yea or nay (without screwing everything up)? Thanks for any help.

Same person with an add-on: is there a way to edit Content Master without "Adding new"? Didn't realize it was adding a new one everytime til I saw this long strip of them , haha - but didn't see any item under Edit or Modify for changing it up. Thanks. (The more I play with the app, the more I see how powerful it is . . . but there are still some things that are just odd, or off. 😕

Hmm, there doesn't seem to be a way to delete a post that you either figured out or no longer want the answer to . . .  NM about either of these. Figured out what needs doing.
