Playlist saving: Internal naming possible?

[lokimus]

Hey Dev's and long users of MusicBee!

I'll keep this short and sweet. I already searched the forum, but I found nothing suitable.
Here I am:

I save my newly created playlist. Ok.
I rename my playlist in Windows Explorer. Ok.
I rename my playlist in Musicbee. Ouch! Problem!
Because:
Here I can rename (in the Musicbee program), but this is not saved "internally". As soon as I import this playlist again, the file name appears, but not the playlist name I just renamed in Musicbee.

1) Is there a way to rename the playlist "internally" in Musicbee permanently?
That would be fantastic!

Second and last question:
(windows explorer -> ) I double click to open a playlist. Ok!
It is also displayed and played under "Now Playling". Everything ok!
But I do not see in the tab "Playlists". But this is what I want!

2.) Can I set Musicbee so that I double-click on the playlist in Windows-Explorer then add it to Musicbee "Playlists" tab?

Thank you very much and hope who good can help me.
Thanks in advance!

Best regards, Lokimus
