Control Point Reference
Reference control points into a project without importing them
It would also be nice and help your control job "clean" if you could suck the data from another job or file. By doing so your work job would contain as staked/survey data and control job would stay intact (like in Leica or Trimble). I think there should be an option added in database section (where you can attach another dxf file-the same should be added for csv file or another project)

Referencing other jobs into a project would also be helpful with multiple day mapping jobs.
