BeatBuddy combining songs/ adding multiple fills help

Hello…new user here. I am having problems combining 2 tunes.

Both tunes have 2 parts, so the new song would have 4 parts. When I try copy/ pasting it only allows me to copy one fill into a given section when I want to copy multiple fills. This is very frustrating. Any help is greatly appreciated. Thanks

I figured it out. you have to copy the fill and paste directly on the “…” to add multiple fills. How this helps anyone else with this problem.
