Add the ability to link a brand domain to multiple business unit

At the moment we can only link a brand domain to one business unit.
This is so limitating… Enterprise companies need the ability to link a brand domain to multiple business unit. Brands and business units are not always linked in a one-to-one relationship. Enterprise companies could have a global brand to manage many business units worldwide:

europe.companyabc.com

america.companyabc.com

asia.companyabc.com

Or by vertical:

health.companyabc.com

tech.companyabc.com

automobile.companyabc.com

Second that!
