Use a standard blocklist for Forms domain blocking

I’m able to paste in a list of domains to block from each individual form, but I’d like a way to manage a blocklist in one place and then choose to enable for each form or not. Whether this is segments or a setting, I want to maintain the list in one place, not have to paste the list into each and every form. If I were to have a new domain to block, I’d currently have to go back and add it to every live form, rather than being able to add it to one place and update it everywhere. With that said, I still want the ability to turn off the domain block list for a particular form.
