How to upload auth proxies via Remote option?

Hello i was wonder is there a way to upload proxies that have auth username:password such as (IPVanish or webshare proxies) with Remote option

The default Pattern is ([0-9]+.[0-9]+.[0-9]+.[0-9]+:[0-9]+) [1]
I tried this Pattern (.*:.*:.*:.*) and it load the proxies but they not work correctly.

Any help would be appreciated if there a way to make it work through remote.
