Sync to Samba Share via GUI [ unsolved ] - eviltoast

I’m looking for a way in Plasma to backup and sync my data from PC to a LAN Samba share on my NAS, using a GUI program.

The many sync apps (Grsync, Unison, Lucky, RealTime, Kup etc.) I’ve tried over many years, don’t let me set a remote/samba target. Most navigate locally only. I would mount the share, but nobody I’ve found knows of a GUI way to permanently mount it.

Everything else I need on Plasma has a GUI solution. Just a sync fails. I’d be grateful to hear of a GUI solution
