Is your feature request related to a problem? Please describe.
My use case today is that I wanted to add a radio with a not easy to search name making it impossible to find in search (at least I have not found it) : Radio G! a French radio.

Describe the solution you'd like
When adding a radio it is searching for radio from a directory from what I understand, what I think would be interesting would be to be able to add it using the direct stream URL. http://46.105.110.80:8000/fluxradiog in my case.
