Assign DEV/TEST/UAT/Staging domains to a production domain.

Currently, some of our rules are not firing in our staging environment (and lower), since they use a domain or subdomain condition and the domain is different from the production domain. It would be nice to have a screen where you could map the (sub)domains for development and staging environments to a production domain. 

In our case, we have multiple domains and subdomains for our environments. A mapping like this would really help to test our code in lower environments:

dev.a.b.local --> a.production-a.com

uat.a.b.local --> a.production-a.com

staging.a.b.local --> a.production-a.com

c.d.e.com --> c.production-a.com

g.e.local --> a.production-b.com

etc..
