Changing the DNS and the server in Southeast Europe for the VPN

CyberDevil

I'm a little frustrated that using a VPN doesn't give me the option to use DNS-level ad and tracker blocking. Could you add a feature to change the DNS to a custom one in the settings? 

I would also like to ask to add a server in Southeast Europe, ideally in Bulgaria or Albania, the server in Prague creates lag in ping for me and I think many other users would also like to have a server closer to them.
