[Zope] Temporary Folder Content - Session Data

Sometimes I feel really bad writing to the list for help. It's when I have very simple, very basic questions. I'm sure that the answer is somewhere, but I've not been able to find it. I'm having a thought that each of my Zope projects that uses sessions should use individual session containers. I had some problems when one of our student developers and I both shared the same variable names. Quite hilarious. However, it seems to be conventional wisdom to store session data containers in temporary folders, as the default session data container is. This of course goes away on a restart. Is there anyway to get them to stick, as the default session data container does? Thanks a ton Edward
