Ability to select delegation zone per domain?

[nielsvr]

This is a feature request, not a bug;

Is it an option to enable a selection in the domain DNS management screen which enables you to choose which delegation zone you would like to use for the domain? Amazon limits the delegation zones to max 100 hosted zones, per which you can request an increase. But the limit is there for a reason. If you have multiple delegation zones on a server, it's hard to manage correctly.

Enabling users to switch and choose a delegation zone per domain would enable more flexibility. Additionally it would be neat to use the AWS API get-reusable-delegation-set-limit to show how many you have used of that said limit.

If you would incorporate it into a paid extension, I would buy that.

Keep up the great work.
