Visual Studio Report Designer for Navision RTC

I'm modifying default reports for Navision 2013 RTC which needs to be done in Visual Studio 2010 report designer.  One unusual behavior I've noticed is with drawling lines or rectangles where the report will shift the fields down to make room for what I'm adding instead of simply drawing the lines over the fields.  I've tried sending the lines to the back or to the front but it has no effect.  Unfortunately many of the default reports use text boxes as spacers so I cannot use the border property of the labels in all cases, especially when drawing vertical lines as there will be a gap between the "header" text box (of a grid) and the horizontal line that separates the header from the data due to the aforementioned text box spacer.  The default report has no vertical lines but I want to add them for the headers only (at this time).  How can I draw lines "on top" of (or beneath) the fields without the report designer shifting and relocating the data elements around my lines?  

The Visual Studio 2010 report designer has much to be desired!
