Draw Vertical line using frill which will grow with the content dynamically.

Needs to add vertical line which will grow according to the content even in next page it will only come up to the content .

Somehow i am able to add the line by using rum macro and frill processing but as i know frill processing will reflect same in each page
, is there any other way that we can implement and find out the specific depth of
the content from starting y position to end y position and grow the vertical line for that particular width in frills according to the data.
