Can I (registry edit perhaps?) change the folder where charts are stored?

Currently they're going to  %Username%/My Documents/SkyDemon/Charts but this is a real pain, as I access that folder from remote machines using VPN. On those remote machines, the time taken to drag the charts across the VPN tunnel is making those SkyDemon installations unusable. Hundreds of Mb of charts backwards and forwards... no go!

I'd like to force the charts to go to a local drive. Happy for the Aircraft, Custom Data, Logs and Routes to stay where they are.

Thanks.
