Not really.
Resilio has a Selective Sync feature, where it keeps an index at each client, and you select which files to sync in the moment. Works very well, I use it to access (mostly) all my media files (but actually any file on my NAS).
I don't replace Syncthing with it because it's very memory intense (keeps the index in ram) and notably harder on battery than Syncthing.
But it works very well - it could replace Syncthing if you wanted.
