Simple I Think F-Engrave Question

I am trying to do some test Acrylic engraving using Easel vs straight F-Engrave sn UBCS

Very New to the F-Carve tool

I want a test that uses 2 - 3 different fonts in the same carve.

Easel not a problem
In F-Carve do I have to create a G-Code file for each Text/Font and run them separately, merge the
say 2 or 3 G-Code file into one, or can I use one than one font in a single F-Carve “file”

Thanks in Advance
