Hi all,

When we go from My client groups → Succession Plans → Add, we get this page:

What we would like to do is to customize the Position attribute; as you can see, if there are multiple Positions with the same name, it is almost impossible to select the correct one, and furthermore, the Department gets populated automatically based on the selected Position.

Is it possible to add more columns to the dropdown list of the Position? (For example Code or Department related to the position), or maybe if we can do the opposite by selecting the Department before the Position, so that the position gets populated based on the selected Department?
