Import RDP files

There does not seem to be a way to import RDP files. But it would be a nice feature ...

Currently I am struggling to create RDP connections in ASG-RD similar to existing RDP files that connect to remote machines through a RDP gateway.
While my separate RDP files work fine, the connections which I create in ASG-RD with the same values do not work. I only get "protocol error"s.
Sure I have overlooked something. But it would save me the work if I were able to simply import a RDP file and it would then work ...
