Add a list type to Custom Fields

Hi,

I was wondering if it would be possible to add a "list" type to the custom fields in a future version of PDQ Inventory?  We use custom fields for tracking the building and departments that a computer is in, and it would be kinda nice to create a drop down list with predefined names to pick from (Building A, Building B, etc ,etc).  This would help keep things consistent and prevent typos, etc.  Ideally we could define what data the lists contained.

Thanks!
