Organize evolutions

Hy!

We have an “old” project with more than 350 evolutions. Is there a way to organize these files to multiple directories? Like 1-50/ 51-100/ etc? It is really hard at this point to find out what is the last “magic number” and also not really user-friendly in most editors to list 300-500 files… I don’t want to modify them, just organize to subdirs.
