Larger text box in treatment notes templates

I have created my own treatment notes templates however when I try to use them on my iPad the text box is too small if you’re using an e-pencil/stylus. It would be helpful if the text box was larger to allow for an better user experience. At the moment even when I select ‘paragraph’ the text box is only one line, it needs to be a text box of at lease 4-5 lines or alternatively it opens up a scratch pad to write your notes.
