I made a starter from the pouch for 200b cells and then took half for freezing and then rebuilt the other back up for the brew that week.
The freezing method was from

I found the same when I had a 4 tap kegerator, if they were in there I just started drinking them.
When that one died I had another larder fridge which I made a 3 tap and then converted a medium chest freezer to lager and condition in at 1c.
Also having the extra space for 2-3 kegs to condition means I have needed to rush finishing a keg to free up the space or the keg( needed to buy a couple of extra kegs
).
