Create Groove Agent 3/4, 6/8, 9/12 grooves from 4/4?

Hi, there are very few grooves other than 4/4 in GA. How easy is it to create a 3/4 6/8 or 9/12 pattern so they fit a lot of the tunes I write?
many thanks, Simon

Posts used to add a list of all my kit but maybe this stopped when the forum changed. For now I use Cubase 11 and Groove Agent 5.
