Button within Buttons for controlling LED show?

[CobaltEcho]

I'm trying to set up multiple shows that change on a button (Button1) press, but one of the shows is a counter that counts from 00-99 on different button (Button2) press.

I can do the "multiple shows that change on a button press" and I can do the "counts from 00-99 on another button press" individually, but I can not figure out how to get one "inside" the other.

Any insights would be apprecaited, code linked below.
