Propagation Mode Reset

[ta2nc]

Hello,
I am not sure if there is shortcut for it or not..
Couldnt figure out how to reset propagation mode status reset

I mean.. assume i made a qso with Satellite and set prop mode according to this..
Then after qso, if I switch to other band or jump across the spectrum via cluster list, I can not select an empty propagation mode unless I make a qso and save.

Is there a "reset to default" mode for logging screen??
