Applying .looks as keyframes

Hello,

I want to use keyframe a .look I saved but I cannot seem to be able to. I mean the clip starts and after an x number of seconds into the clip I want the .look applied. I've tried adding keyframes and then applying the look but as soon as I press enter to validate the look all the keyframes up to that point dissapear. I'm using Direct Link mode from Premiere.

Keyframes need an overhaul in Speedgrade, they are pretty clunky at the present.

thanks.
