Session Host sub-entries are hidden in "prompt on connection" dialog window

We need to reduce the number of visible entries in the Tree View and we've found that a good option might be to use the "Host" session entry for each system/device/computer (etc) and "sub-entries" for each type of connection to it (rdp, web, idrac/ilo, ssh, etc.).

The problem is that if we disable/uncheck the global option "Load sub-entry in tree view" to hide all sub-entries they are neither visible in the pop-up window when you double-click a Host session entry that is configured witth the "sub entry to launch" and "prompt on connection" options on it.

Could a new function or option be added to make the sub-entries always visible in this window so I can select them even if the are hidden in the main Tree View?

Much appreciated.
