Highlight Text box code in reveal codes

I have large documents with many text boxes. I use them to insert tables to get a wrap around feature that tables alone do not offer, and I use them for illustrations that I want to the side of text. It would be enormously helpful if, when we put the cursor in the box in the document if the text box code would become highlighted in reveal codes. At times it can be very difficult to find a text box code or to distinguish between multiple codes as to which one I want to edit (usually this is required when I am trying to delete an old version and replace it with a newly revised text box).
