Expand any given tree view session entry folder with a double-click

I have a few hundred RDP session entries sorted into many subfolders and it's very slow and inconvenient to have to click on the left expand arrow for each session entry folder I want to expand. I know there's an option to expand all, but that requires using the right-click context menu, plus I don't want to expand everything, just one folder at any time. And I want to be able to double-click any expanded folder and have it collapse as well.

I have searched everywhere in preferences and in properties for each folder and can't find a toggle to set the expand/collapse behavior of session entry folders in the left sidebar tree view.

Is this not a feature or am I just not finding the option?
