Let users decide which root path is used

[henningBunk]

Is your feature request related to a problem? Please describe.
I am having multiple root paths for radarr (movies, documentaris, concerts) and sonarr (series, documentary series). Right now, when a user would wish for a documentary, documentary series or a concert, that content would be added to the wrong path.

Describe the solution you'd like
The option not to choose a fix root path in the radarr/sonarr settings. The user can decide a root path before the request is send.
It would be great to give the root paths friendly names which are displayed to the user:
/array/media/video/movies -> Movies

Describe alternatives you've considered
Some kind of programmable logic to automatically choose the root path for each item. In my case something like "genre contains 'documentary'" would help, but I don't know how other people use their root paths and maybe this is to rigid.

Additional context
None.
