Assign Dimmer Card types in Dimming and Control

Hello.

I work in a new venue.  We have seven house sensor racks with many types of dimmer cards (ie. CC20, D20, TR20AF, etc.....).

I think it would be helpful to be able to manage their types and physical locations in maintenance lists.

Has anyone found a method for inventory tracking this information?

Any suggestions would be appreciated.

Thank you, 
Brian
