When I am traveling I defer working on the photos until I get home to a computer with a decent calibrated monitor, but I like to back up the photos from the camera at the end of each day, and do some first-pass selection.
However, everything ends up in different film rolls. Is there a way to add imported images to an existing film roll?
There is a 1-to-1 relation between film rolls and folders in the system. Pictures in different folders go to different film rolls, and pictures in the same folder go to the same film roll. There is no way around it.
If you want to group images independently of that, you may use color labels (for something more temporal) or tags (for something more permanent).
As discussed in the issue, there are various workarounds, all involving multiple steps. I opened an issue because it would be convenient to just do what I want in a single step (import into same film roll directly from camera).
If I understand the “Copy and import” dialog correctly, then import options are retained between sessions. So if you set up the import once with a fixed subdirectory name (and job name, so no $ variables), subsequent imports should also go to that subdirectory.
So that would mean:
first import of a series, you have to enter a name for the target directory
subsequent imports will go to the same directory, until you change the target directory
So if that describes what you want, there is no need for another code path.
Of course, if you keep the defaults, each import ends up in its own subdirectory, due to the $(YEAR)$(MONTH)$(DAY)_$(JOBCODE) variables in the directory name.
