Hi Chip,

I believe you need to create a function that extends Ens.Rule.FunctionSet which should then give you the option to select this function within the UI or for usage within the DTL as well depending on your preference of course.  Let me see if I can find an example for you.  Note: I simplified my code to fit closer to your ask, but I did not test it.

Thanks,

Chris
