### The problem

Hi ,
I think there is really useful to be able to make a group of domain names in "DNS rewrites" menu and can enable or disable the group instead all domain names one by one . Most time we need to redirect a group of domain to 127.0.0.1 :)

### Proposed solution

it is a suggestion
