_I would like to see the ability to have custom property fields linked together, so that if I select an item in a dropdown for one field, then other fields would auto-populate with information.
For example, I could have an drop down field to select Site Name. Once I select the Site Name, I would then like the Address, City, State, Zip and TelephoneNumber fields auto-populated with that sites info.
Another example would be if I select a carrier/telco from a dropdown, then that carrier's telephone number would auto-populate in a field.
A more complicated example would be if I had Site, Floor, Room fields. The Floor and Room dropdown would be blank by default. Once I select Site, Floor would autopopulate with the Floor options for that site. When I select a Floor, the Room field would autopopulate with the room options for that floor.
