Interact Auto Concatenation of Fields

[mcandrewe]

I would like to be able to create a hidden field which concatenates values entered by the user. This would prevent bridging queues, processes or other means to create an appropriate key.

We have a process where the key value is a concatenation of the member number and a contact method. This is to allow multiple requests for the same member but also identify duplicates. We cannot replicate this directly in an Interact form.
