Perspective Vessel Scaling

I'm working on a coordinated view and I am attempting to use the Perspective Vessel object (to show level of the tank). I'm trying to expand the size of the vessel where I can have the vessel expand in the open space on the screen shot.
eq_perspective_vessel

When using a symbol from symbol factory, I saw a prop preserveAspectRatio that could be set to none. I am not seeing anything like that for this. Any ideas?
Thanks

Hi,

Are you familiar with style properties in Perspective, specifically the overflow style? Perhaps you could use this to manipulate your object a little further.
