No problem! This seems to be one of the few things that isn’t documented all that much anywhere. I feel like I’ve looked through all of Google so far! Haha.
Seems like it’s something a few people are looking to achieve, but yet all I find it people pointing people to the “Dynamically populating a select field” post, which I’m sure you’ve probably seen as well!
Hopefully something relating to this issue appears soon.
