drag and drop - creates a new category. (cannot add to an existing category)

[NetworkDifficult]

Hello. So far everything has been great, but this one issue I cannot seem to solve regardless of how much I fiddle with the playlist options. I have the default playlist, with 3 sub-categories. Now, I want to add a single track from a certain folder under one of said categories, but drag and dropping creates a new category (with the name of the folder in which the track is).

Is it possible to add my track to the existing category – the folder of which is somewhere else – in-app, without having to move the track to my main music folder? If so, what settings should I tweak? If not, will you add this feature?

Attachment #4: Desired result (without having to externally move files)

Categories creates automatically based on metadata of file that it contains according to settings. You cannot move files between categories.
