ORD - Profile Drawing Production: Tabular Data - Graphical Lines

Good day,

I would like to find out if it is possible to customise the Profile Annotation Group to change the way ORD generates the tabular data for the horistonal and vertical data. I am specifically pointing to the way it generates the graphical lines. Currently ORD generates horisontal and vertical curves as "graphical curved lines" whereas our preferences are straight lines with dimension arrows (see attached image below). 

From a high level observation it looks like these graphical lines has been setup in the "background" of ORD and can't be manipulated(?).

I hope this observation is incorrect and there is a way to manipulate these graphical lines. 
I would really appreciate any help.

Many thanks and kind regards,
