I have three domains on vercel and need to make two dyndns entries for my two sites. I either have to do some magic, use weird docker images or give up on using my vercel domains for dyndns. My .dev domains costs 5$/month more than on my previous or different provider, so I'd expect to have a more premium experience. Meanwhile, other DNS services offer this for less money. AFAIK, all that would be needed is to update existing entries programatically with a technical user / credentials with very limited access. (Would be used with a unify controller)

I'm not asking for a weird workaround, but for it to be officially supported. I know I'm not a big customer, but if this gets stale, i will move to a different provider.
