I only have 2 Pullman pans but I’m committed to making 4 loaves. <(‘ .’ )>

I didn’t know until now that there is such a thing as over proofing dough. Whoops. 😬 what should I do with the other half of my dough while I’m proofing, pre bake, in the two Pullman pans I have? Can I slow it down by putting in the fridge?
