I assume you are on Windows 10 PC?
When you save a track template you can naviguate to your Synth Folder and right-click it and choose "Pin to Quick Access".
A shortcut of that folder will appear on the left panel for next time.
It's not as fast as saving it directly like you asked but at least it's less annoying then to naviguate trough each folder each time you wanna save a synth.
if you figure out a way to do that, let us know
