Using A/V from different URL sources

Greetings,

I am interested in purchasing the AM6B+, but I would like to confirm whether CoreELEC supports playing two distinct Real-Debrid URLs simultaneously — one for video and another for audio — similar to what is possible with MPV/MPC on a desktop.

The reason I ask is that, as a non-native English speaker, I often find high-quality 4K remuxes available only in English, while the audio in my native language is typically available only in lower-quality video sources. Being able to combine the two would greatly improve my viewing experience.

Thanks in advance.

Banned addon means no support.
