Currently in Box it is not possible to drop in a signed field (e.g., Company Name) and have that display perfectly within the body of a paragraph. A great example of this would be a Non Disclosure Agreement which traditionally has the name of the organizations in the first paragraph. While you can drop a field in the approximate location, the sizing will not gracefully adapt to the entered text and it always looks slightly off compared to the rest of the document (e.g., alignment, placement, font, etc.). In other signing tools there is a Word Toolbar that allows you to drop in field attributes and the content experience is seamless.
