So I just figured out that my 4PKS-R can fix this problem. I can set the brake so that when it is engaged it automatically jumps away from neutral to the point where the slack is taken up and the rest of the response from that point is linear so its not like using positive expo. Haven't had a chance to test this out but looks like a really useful feature. For those with a 4pks-r it is explained on page 52 of the manual.
