Project Merge - prioritise a specific project's images when there is overlap

I am trying to merge many projects with differing levels of image overlap.
Some of the images were captured in better light, so I would want to prioritise using those for output and also during processing steps.
Is there a way to prioritise certain project imagery within merge processing?


When merging the complete project is used, you can’t select any specific part, unfortunately.
You will have to process again taking these images out. and afterward, merge.
