VFO's A/B switching between bands

Is it possible to set VFO A to one band, and VFO B to a second band?
I recall some discussion about this in the past, but do not remember
if it was on a tudo list, or if it will be a limitation.

As an example, place VFO A on the 20m band CW mode, and VFO B at a
location on the 40m band CW mode. I have done this with other rigs,
is there a menu setting I am missing, or a limitation of the rig? I
just did a couple of quick searches through the documentation, but I
did not see a reference to it.

I am using the 2.20 firmware. I see that it is supported with the
sub-receiver.

It is handy during a contest to set VFO B to another band, and bounce
there periodically to check activity / propagation, while CQ'ing.

Amazing what you remember right after hitting the send button. Like
putting K3 in the subject.

Re: Re: VFO's A/B switching between bands

Based on this, I thought it might be on the Tudo list. But then I
recall a firmware fix that addressed a cross-band problem. So I'm not
sure if they are addressing that issue, or the using A/B between bands
issue.

Re: Re: VFO's A/B switching between bands

Just to clarify, I am asking about using one VFO on one band and the
other VFO on another band. Same antenna. No need for a second RX.
Historically this has been a basic capability of transceivers like the
IC-706MKIIG.

I do not expect to hear from both VFO's at the same time. Its an
either or thing. VFO A on 20m, VFO B on 40m, hit the A/B switch to
toggle between the two. Check and see what is going on, on 40m.

The choices that I see are;
This is on the list. If so, no problem, I can wait.
This is not, and will not be a capability of this radio.
I have missed a menu setting that will let me do this.
None of the above.
