Can I edit an XLAM addin while others are using it?

I think the answer is "No", but just checking...

I've got an XLAM addin containing a class definition. That class definition has the bulk of the code for my Excel application.

There are 4 end users / 4 workbooks that have this XLAM addin as a reference. So, when any one of them open their workbooks, the XLAM addin is locked, and I can't edit it.

Is there a way I can have the addin editable while they are using it? Perhaps with readonly permissions, etc? It's a pain to ask them all to close down their workbooks whenever I need to fix a bug or enhance the addin code.

I'm happy if they have to reopen their workbooks to get the changes, I'd just like to make the changes while they are still working.

Thanks,
Scott
