Random on all folders?

[MicBeast]

I've just got a "NORDIC" MPX player that looks kind of like this one:


(Except mine has slightly different menu icons.)

In music mode is it possible to play music randomly over all folders or root dir? I can use all "repeat all" to play them all, but then its not random.

I would rather not place all my songs in root directory as sometimes I only want one artist...

Is this possible? (maybe it exists in a newer firmware?)

Thanks!
