@jacobtylerwalls, @chiatt - Unless I'm missing something, I think this should already be available in the config parameter. This is how I'm determining this in my custom descriptors:

            if config["type"] == "name":
                .... logic ...

A full (not super clean) example is here: https://github.com/bcgov/BCHeritage_arches/blob/main/src/arches_bchp/arches_bchp/pkg/extensions/functions/bcrhp-site-descriptors/bcrhp_site_descriptors.py

Thanks for linking out to your implementation @bferguso. That approach would require altering the function config.

What do you think about the current approach on this PR? Is it a benefit that the function configs wouldn't have to be altered?

Hi @jacobtylerwalls - I think that makes perfect sense. I'd forgotten that I'd modified my local function configs to make it work so I think what you've proposed is great.

Looks good!
