Track any site with wildcards

Hi - In my case, I add following to my tracking code:

_paq.push([“setDomains”, [" .xy1.com"," .xy2.com","*.xy3.com"]]); to track several domains and subdomains which belong to the same project.

Can I wildcard setDomains somehow to track all domains and subdomains? Eg.

_paq.push([“setDomains”, [" . .*"]]);

That would help a lot because I don’t want to change the tracking code for each new domain/subdomain.

Thank you very much for your help.
