Antenna switching question

Currently I have five antennas connected to my K3S via a manual switch:

LPDA, 20 through 10
Vertical, CW on 80, low end of 40, 30, 20, 17, 15, 12 and 10.
Dipole, Phone on 75, phone on 40, 20, 15
Inverted-L on 160
Yagi on 6
Mostly the antennas are below 2:1, but they need some flattening on 160, 80
and 40 if I have to go beyond their sweet spots.

When I build the KAT500, what is the best use of the 3 ports available to
maximize it's tuning algorithm?  In other words, how can I maximize the
likelihood that a band change or QSY will result in a rapid tune due to
prior memorization, versus a somewhat longer full tune?

My thoughts were perhaps to put the 6 and 160 antennas each on their own
KAT500 port, then use the manual switch for the three that would cover HF.
Fine, except there could be a situation where the KAT500 had memorized a
tune for 7.100 that might be fine for the vertical but different for the
dipole.  The vertical is omni, so at times it would be a better choice than
the dipole.

Or, perhaps experienced users can tell me that the tuning works quick
enough that even if I try to confuse it the KAT500 will be quick enough
that it isn't an issue.
