Sampler Transpose & Detune Automation Lanes grid sync

[floond]

I was messing with some transpose automation on a sample in Sampler, and in certain areas wanted to make a more smooth transistion than semi-tone steps, so figured I could make some +/-50ct sweeps with Detune automation. I made some individual automation lanes for both parameters, so I can see where I am on the Transpose lane, and make fine adjustments on the Detune lane. But, when scrolling the +/-48st grid vertically in one lane the grid in the other lane moves as well making my task next to impossible. Is this a feature or a bug?
