Add the option to set a Numeric attribute to auto-increment

Feature Request Summary: 

ConnectMaster should have the possibility to set a Numeric Attribut as Unique and Auto-increment

Functional Area / Module: 

Attributs

Description/Use Cases: 

We manage our Locations by a unique ID number Attribut. It would be useful that CM create a new auto incremented ID when a new Location is created.

Business impact of limitation or missing of the feature:

Without this feature, Location IDs must be managed externally in an Excel file.
