Any Way To Set Default Target Directory For File | Export STL?

In SU Pro 2016, is there some method of setting the default export directory for File | Export STL?

Have you looked at the options under Files in Preferences?

Well, yes, but that seems to set a default directory for ALL model
export actions.

Since I usually export .STLs to the laptop on my LAN that controls

the 3D printers, I wish to limit the Export STL menu option to
target that remote directory only, with all other Export actions
going to the preset default or a newly-browsed destination.

Thanks for your timely response!
