Please increase the max mount settle time?

I have a Vixen GP-DX that has terrible backlash in declination and takes forever to settle after a meridian flip – as much as 600 seconds. The mount settle time I can enter in SGP stops at 100 seconds. Can this max number be increased? I realize the mount is a problem but until I can get it tuned up, it would help a lot if I could automate meridian flips – the cap on settle time makes that difficult.

Thanks!
