QSL labels


I'm trying the N3FJP logger as I'm planning to switch.
I modified the window to my needs and like.
Two questions, next to the callsign entree I added a VIA entree box. Is there a way when you print the QSL label to include the VIA callsign?

Also, is there another way to do a clear, instead of  having to click on the clear box?  like a CTL + something ?

Thank you,
