Checkbox for "Do Not Import Duplicates"

[frozen-cdn]

I keep continuously wasting time importing the same proxy IP addresses that show up as different protocols, but are already tested and confirmed as bad proxies.

I'd rather just leave one marked as NOT WORKING and then will no longer import any more proxies with that IP address

Could you please make an example to make sure I understand the issue? Can you show one or more sample proxy groups, what happens right now that you'd like to change, and what you would like to happen instead?
