Can document manager get to and change text in the sheet format.

I need to change my custom property links in the title block in a bunch of my existing drawings.

I need to change \$PRPSHEET:"Part_Number"  to  \$PRPSHEET:"PartNo".  These are in the sheet format when you right click on the drawing and choose "Edit Sheet"

Can this be done with document manager?

Thanks,

Dan
