Dynamic Population with Field Names

Does anyone know of a way or some additional code to use Dynamic Population not just on the field value, but also the field name as well?

Basically I'm having price data come over from another form (a non-Gravity form) via query strings with product options, for example: Neoprene_Hose = 20.00.

However, the next product might not have that option. It might have Silocon_Hose = 30.00.

I've gotten around this by having hidden fields generically labeled "Option1" (with as many as 10), with a ForEach loop that renames the $_GET key to "Option1" and puts the original key$ in the value$ for reference. (with a counter moving up until the For Each is done.)

This does work, as the email that gets sent out lists Option1, Option2, etc. But I was hoping to dynamically change those labels to the original key$ (Silocon Hose, Neoprene Hose).

I guess what it really comes down to is the first form, the non-Gravity form, isn't always static. It's form checkboxes and radio buttons can change, and I was hoping I could have a single Gravity form work with this setup somehow.

I'm guessing not, simply because then what would the field names say when you actually browse through the data in Gravity Forms?

I hope that makes it more clear. I'm having trouble explaining it myself. :)

Worth a shot. :) Thanks very much.
