PS version 6 shared code

Hi anybody with some experience with PS 6.0?

We have several workflows&processes that share WF/PS code located in a separate directory. When this shared code is modified, then it does not need to be modified for each workflow/process that uses it.

What we understand with Workspace and Projects, all code and files should be within this area and that would take away this capability.
If this is correct, any idea on how we could accomplish the shared code issue?

Any help will be appreciated.
