maintain numbers in succeeding impress slides

I’m trying to create a simple presentation. The first slide is broken down into bullet point letters. ie
A.
B.
C.
D.
E.

I would like to carry over each letter to its own slide. So,
A
1.
2.
etc

Cannot for the life of me figure out a way to do this without manually entering them as A, then B, etc. Also, if you want to indent a bullet letter (whatever it’s called), or in this case a manual letter, the only way I can find to do it is enter manual spaces.

Is there any easier way?

And yes, this is just a blank presentation at this point, no theme, and that’s because I don’t yet know what theme will be applied.
