When running multiple jobs for testing out different processing option settings, I create a project for each one, but reuse the image linked GCPs from the initial run. Select all GCPs from the first project and use the Export Control tool to create a ZIP file. This file can then be imported into new projects with the photo links already generated.
Hi Anna. I generally will go to the Project's folder, and copy any products into a new folder outside of the project for safe keeping so I can compare them after my next processing run. Hope this helps.
