How to shape sourdough without banneton

To be clear, I have bannetons. I am looking to shape and bake sourdough without needing anything at all. I'm looking to create smaller and longer loaves, I was thinking I could football shape them and put it directly into my stone oven. Has anyone ever attempted this? When I look up suggestions online to baking without bannetons, it tells me to use bowls and colanders but I need to make a lot of loaves in a small amount of space. I don't have room for the Bannetons. Help please. I want to donate more this month but i'm struggling to find a space saving way for shaping for the oven. Maybe like a large baguette shape?
