Multi-lined Text Field in Writeback Editor Mode

I have a field that was filled out in a writeback form that was a multiple response checkbox field so the contents are long. It looks like this: 

Within a text box, i break it out into subfields 

So then each subfield is on it's on line

However, when I put that subfield code into the text in the writeback table form editor, it does not respect the chr(10). In addition, the text box isn't large enough to accommodate the field when it is not broken down into subfields.

It would be nice to be able to expand the size allowed for in the text field and also to be able to use the chr(10).

Thanks!
