Multiple Administration Roles in Project Contracts

Is there a way that the Project Contracts System will allow an internal employees (Administration Tab) to have 2 active roles on a single document. John Smith could be set up as both Program Manager and Technical Contact.  We often have the same person filling both roles.

I understand the Access Security being an issue with assigning the roles, but if the two roles in question do not have a security assignment would it make a difference?

Program Manager and Technical Contact-we do not have any security set on these roles.
