Adding Read Only Text in Digisign

Would be nice to be able to add more than 500 characters of text in a Read Only text box.  Such as when adding text to a BINSR (page 2 seller response area) greater than 500 characters is frequently needed.  When 500 is exceeded you have to create a new box, but it looks really bad on the document when you try to put the text boxes together (it adds big spaces between the boxes and does not looks good).  Also the spacing doesn't match up to the document and sentences look crossed out.  Another e-sign program (docusign I think), puts blank space when adding text so there are no lines which looks better to me.
