A solution I had for a similar problem when I was still using Notepad is find a file you've previously written WITH quints in it, open it in Songwriter and save it as a new file. Then, just use that as a template for anything you want to write.
It's an imperfect solution as you're limited with time signatures and arrangements, but I did it with a basic snare/tenors/bass/cymbal combo and wrote any cadences and warm-ups with that. Better than nothing!
Hope I helped!
