[amsat-bb] SatPC32 leading the satellite

I was at a university ground station today and noted their antennas were
not keeping up with their satellite on a high elevation pass. They are
using SatPC32 with the G5500 rotor. They have the dead band set to 3
degrees. Since they are using a pair of long UHF Yagis for a total of
21dB gain there were some lost packets for about 2 minutes or so around
TCA. Their sat was deployed from the ISS so is currently at about 400km
altitude which means it's zipping by rather quickly when the elevation
is above about 75 degrees or so.
In the past I've used tracking programs that allowed a 'lead' setting.
That is, you could tell the software to lead the satellite by a few
seconds. That did a pretty good job keeping the sat in the beam width
when the AZ was changing quickly. I'm not finding that setting in
SatPC32. Is there one, or another setting to accomplish the same thing?
