User Manager Properties

Hi,

I have to create a TS User Management for my organization.

To keep it simple I would like to use the built in TS User Manager. BTW I need some additional properties in user's type definition.  For changing the properties I would like to do it by calling Engine.DisplayEditUserDialog method. As assumed, my properties are missing in this Dialog.Is there a way to override DisplayEditUserDialog to get desired behavior.

User Properties Desired
