As of right now, if Zapier is used to create an item, it can almost do everything. In fact, it can do all sorts of neat things like setting IPs and statuses that I didn't even know were in the software, but oddly it cannot fill in Meta Keywords or the Meta Description on the pages app. The only other fields it cannot seem to utilize are upload fields and I can write that off as a technical thing, but the Meta Fields are just text-based.
Maybe I have missed something? But with how great AI is for meta details, I feel like this is a lacking option.
