A difficult question regarding casual and normal playlists

[Pidgeon]

Hi everyone, I have 2 playlists:
A - 10 tracks
B - 5 tracks

I choose to play random tracks from tracklist A (so that everytime I start playing playlist A from scratch, order of the played tracks is never the same).

I choose to play sequential tracks from tracklist B (so that everytime I start playing playlist B from scratch, order of the played tracks is always the same).

The question is:

If I choose to play 3 tracks from playlist A, and then I switch to playlist B, and then I swtich again to playlist A, how would it be possible for me to avoid the playing of already played tracks from playlist A?

This mean that this is the result I want to obtain:

1) I listen to 9 tracks of playlist A.
2) I listen to playlist B (full or partially, doesn't matter).
3) I select again playlist A: the last and only remaining track will be played (so that 9+1=10 tracks), then playlist will stop.

I hope my question is clear enough .

Bookmarks+shuffle playlist works, so problem solved.
