Checkbox for dns list

[nunu6689]

Good morning sirs.
Can we have a checkbox for enable/disable instances?
Something like in the firewall list. So we can switch dns faster.
Thank you sirs.

Technically possible, it would require modifications to the principal package as well tho. If someone were to submit PRs I would accept them, however it wouldn't be too high up on my priorities list.
