This was mentioned I think by Ben Sachs in the original feature (https://feedback.savvycal.com/feature-requests/p/custom-doma…) but seems to have only looked at the second part rather than the first.
I have a personal profile where people can book time with me directly (under meet.me.com) but I also want to echo my booking links under the company domain (meet.business.com/rudi). Currently when I tried to do this it transparently removed the meet.me.com mapping to the root domain, leaving me only with the business one.
It would be great if we could do both!
(Workaround: Create a "Team" (that's just you) and re-create the links in there matching your own personal branding).
