Workaround For Needing To "Un-Flatten" A Multicam Sequence

I may simply be out-of-luck on this one but Premiere Pro is a vast land of options and opportunities so I figured I'd put it out there. I have built, edited, and exported a project that started as a multicam sequence. At some point towards the end of my workflow, I flattened all of the clips. Now, some revisions on the edit are needed and I'm wondering if there's a way or a workaround on regaining the state of the sequence before it was flattened. It's not the end of the world but it sure would save some time if possible.
