FR: Export flow - only add players in use

If it export a flow of a project with lot’s of players, all players will be exported, even if they are not used in the flow I want to export.
I would like to have an option, where I can choose to export only the players used in that flow.
(If this is already possible, please lead me to the according setting.)

If you don’t tick the option to export each layout separately, Dorico will export a file that contains all players included in the original project.
If you do tick the option to export each layout separately, Dorico will export a file that contains all players included in the selected layout.

I guess the only solution right now is to create a new layout that only contains the players you want, then export specifically that layout.
