HELP NEEDED!!

hi can anyone answer my question here.. thanks.

I am doing a caramelized onion and cheese roll bread. the question is, can i leave the ready made bread ( as in it's already stuffed with filling and cheese and cut up and placed in baking pan) in the fridge first? I was supposed to leave it till for a second rise but I have something to attend to last minute.. So can i do that? will my dough or the filling go bad? can i leave the dough with filling in fridge overnight or for a few hours? Appreciate any answers. Thanks!
