How about A/B, adjust filters, A/B? 

This seems to work here. You can set the filters using the main controls,
then the A/B transfers them to the sub and brings back the original main
settings, frequency and mode.

There is one exception to this (is this a bug or a missing feature?): the
RTTY dual-tone filter. It seems that the only way to have the DTF set
differently on the subRX than on the main is to use BSET. After you set or
clear the DTF in BSET using the DUAL PB button, the change also applies to
the main RX (this does not appear to happen with other filter settings), but
you can reverse it with the DUAL PB button without affecting the subRX, so
you can have DTF on in one VFO and off in the other. However, when you do an
A/B or turn the subRX off, the previous VFO B DTF setting is lost and it
reverts to the same DTF setting as the main RX.
