    The two issues are unrelated. if you have several rools of B&W film that require the Same development time, you can run them all together. If they require differing times you can't. Does not matter what ISO they are originally.

    If you are using a developer with a long time it is likely the ideal time for more types of films will be close.

    As far as COLOUR film the normal standard process for colour negative these days is C-41. It does not matter WHAT c-41 film you chose, they will all have the same colour development time and so can be batched to gether in your favourite C-41 Process.
