Change Root Directory

I installed Portainer using the Synology UI which correctly placed the volume in /volume1/docker. Now if I create volumes from within Portainer they are created at /volume1/@docker which is outside of the Synology share and limits what I can do with it (I.e. snapshots, etc). Can I change Portainer to create volumes in /volume1/docker?

Lookin at host > root directory it shows “/volume1/@docker”, I guess that is what I need to change?
