I've done it a few times, but only with bread in loaf pans. I'll treat it the same as regular bread up to forming the loaves (I usually kneed, punch down, then form loaves for the second rise) and then freeze. Thawing is tricky though. you don't know how long it will take to thaw, and then it needs to rise. I'm in a cool climate so it takes me 4-8 hours just to thaw, another 1-2 hours to rise. Me, I usually let it thaw overnight when I have a free day following, it's hard to plan when I'll rise. You could also let them thaw in your fridge in a bag. I'll take longer, but you can control when they rise.
Another solution is to freeze it in flat disks. Thaw faster, but take up more room. When they are thawed you can roll them up into the loaf shape and then let them rise.
Hope that helps.
