[mythtv-users] Repack - Rescan question

I am trying to plan for the upcoming repack. I would like to do this with a
minimum of "learning" new ways to do things. My basic question is can I
scan a narrow range of frequencies in order to add a new channel to an
existing lineup without that deleting the existing channels?

Here is the background.  Right now a local station KTVU transmits on the
old station, 44 and the repack station 31. Both come in great. It also
transmits on 26 which comes in poorly as it is hitting the back of my
antenna. There is another station, KGO that is moving from 7 to 12 that
also transmits on 35 into the back of my antenna. Both the San Francisco
versions that I can get and the San Jose versions that hit the back have
the same call signs although they might have different xmltvids. What I
recall from past times is that if Myth scans low to high, I end up with the
wrong KGO and if it scans high to low I get the wrong KTVU. I am not sure
of which way it scans or even if it does reject duplicate call signs that
have different xmltvids.

Ideally I could just set the scan to go from 31 to 31 and it would just
find the new KTVU and I could manually edit out channel 44 if it isn't

Another idea I had was to add attenuators until the back stations no longer
came in at all and then scan but my hope is there is an easier way. The
repack is 4 stations of which 2 have both SF and SJ versions. Not sure if
that would work though.
