Scrolling problem with positions

I have a problem when scrolling in the planner grid.
When I have
positions that ar larger than the height of the grid (if position is
left), and in this position there are items that are in the same
timeslice, so that they overlap, it could be that some items are not in
the visible area of the position. When you scroll down, it does not
scroll to the not visibkle area of the same position but it scolls to
the next position.
So what I need is to have a smooth scrolling within a position.
I did not find a property where I can tell the planner to do so.

I hope you can understand what I mean.
