Gear ratio up to 14/1

So I have an oxy 3 with 140t main gear and 10t motor pinion. The software only allows me to go to 12.7 ratio but I really need 14. Is this a limitation or can we get to 14 with a software change?

Previously there were same questions about this issue with solution. I will try to find it.

Have a look at this:

If I understand it correct, by doubling sensing divider and halving gear ratio, you should end up with same rpm.
Motor field rpm = rpm * GearRatio * SensingDivider = rpm * GearRatio/2 * SensingDivider*2
I hope higher gear ration will be introduced in next minor release.
