Rollup Properties should support a union of drop down properties

I have dimensions on Contacts in a multiple checkbox drop down associated with a Company. I would like a property on the Company that contains a union of the values of all the Contacts on the Company. The best way to do this SHOULD be with a rollup.

Like this:

  • Contact A
    • Positions: Center Field, Right Field, Second Base
  • Contact B
    • Positions: Short Stop, Third Base
  • Contact C
    • Positions: Third Base, Second Base

Given that (and the contacts associated), the rollup on the Company would be:

  • Rollup Positions: Center Field, Right Field, Second Base, Short Stop, Third Base

Workflows are not a great solution because of the logic required to consider the permutations and this is WAY overkill for spending credits on an agent or custom action etc.

That is a great idea!

A join property would be super useful!
