Is it possible to combine lists of user waypoints loaded on different machines?  Saving to the cloud from a machine completely overwrites the list on the cloud, and loading from the cloud overwrites what's on the machine.  

Some of us on this forum have been asking for this for years. I’ve accidentally overwritten and lost waypoints in the past because of the current solution so I’m now very very careful when backing up etc.

A better and more consistent cloud solution is needed. At the moment, waypoints, aircraft and routes all use different methods of backup and retrieval.

This is in need of decent consistent redesign but with a lot of feature requests like these, SD believe it’s “their train set” and they’ll do whatever they want.
