Depoy or Scan Multiple domain names but same computer

Lets say we have a domain called contoso.com and John's laptop is now John.contoso.com

John isn't using a VPN, but John has a program installed that still lets PDQ scan and deploy to his laptop at home but it has to use the name john.contoso2222.com provided by the program to connect.

Can PDQ deploy/inventory to a FQDN and then failover over to the second FQDN if the first one can't be reached?

I know there is documentation about multiple domains, but this is one provided by a program (can be changed to anything) and not an actually second company domain.
