Hi, I know this is very late and the issue maybe solved but it seems simple to go into the Piano Roll up the top where it says View/Edit there is a dropdown set it to Pitchbend then in the lower portion of the Piano Roll screen put in your shape.

It is much easier in the system I use where one can simply use a line similar to the volume on a track. I don't know why the option only has volume and not others but the the Piano Roll works fine albeit a bit harder to use.

My thoughts
