Yes but it's easier to just add whatever you need in Pro Tools.
Pro Tools is a complete D.A.W,i think a lot of people forget that you can do more than just mix
and master in it.

You can rewire FL Studio to Pro Tools or use FL Studio as a VSt inside of Pro tools to use the original FLP of your beat and add elements from there
without moving files all around here and there
