Allow Custom Work Item Fields to be populated from an external Source (DB or WS)
At the moment there are only 2 ways of populating the allowed values list in a work item. In the work item definition itself or in a global list. Some more flexibility would be great here. Besides that. Allowing a list of values to be displayed as a tree would be great as well. Not limit this only to the area and iteration field. Another solution might be to enable non admin users to add values to the allowed values list without "hacking" in the work items or Global Lists

Thank you for creating this suggestion. Current work item customization is all great but we constantly have need to add external dropdown fields from DB or Web services. This can be done in combination of more WI custom controls.
