Can I assign more than one role to a user

Currently, Breadcrumb only allows one role to be assigned to a user at any one time. You can always change the role that is assigned to a user from Breadcrumb HQ.
If employees frequently work under more than one role we recommend creating two different user profiles.
For example, if Jim works as a server on some days and as a manager on other days, you can create two user profiles for Jim:

Jim Server
Jim Manager
Each user profile has a unique PIN code and if the role has access to HQ, a unique username and password.
