[Dx4win] Transverter offset

[Mike]

Hi all!
Not long ago I start to use my 2m transverter with my IC-7700. The I.F. for
this transverter is 28 MHz. To log my QSO on 2m correct, I activate
transverter offset (File-Preferences-Radio).  It working fine, but if I need
to log QSO on 10m, a have to cancel transverter offset via File-Preferences.
Is it possible to do that without changing preferences every time just with
one key on the fly?

Regards,
