"Prompt for Host" does work for Sub Connections

We like to have our main connection to a server RDP for obvious reasons, as sub connections its good to have iDrac/iLo, "Citrix (Web)", although "HTTP/HTTPS" seems to work now (I seem to recall it not previously).

The ISSUE: When you right click the subconnection and click "Prompt for Host" this is a flicker, no prompt, and the primary connection just opens.

This is a cause of frustration as you are forced to have 2 subconnections (we use secured portforwards not a VPN to access remote sites). 1 for remote access to a wan address and port, and another for lan access to the same device.
