"Playing now" option on quick screen on Sansa clip + ?

[Rollmops67]

This is my first post here, and to begin I wish to thank all people who contributed to Rockbox.
One week ago I even didn't know what Rockbox is !
I installed it on my Sansa Clip +, and all works as advertised.
It's like changing from a Ford T to a Rolls Royce !

That's just one thing I did not figure out how to do :
I would like to add the "playing now" choice of the main menu to the quick screen, but I see no way to do that (perhaps it's impossible ?)
When I do a long select on "Playing now" I have no choice to add it to the quick screen...

Does someone have a clue ??

Thanks in advance for your answer.
