my CPT is prepared to upload one "main image" which will be used for the main content of that custom post.
This will be used as featured image as well
The image-upload is placed in the CPT-form in a logical sequence, the "sidestep" to the "featured image" will break the logic of the workflow
is it possible to do this or do the users have to choose this uploaded image in an addittional step as "featured image"? If they have to, I am sure they will forget that very often..
