Stylus only works free-hand?

I just got a surface and surface pen and want to use to annotate in Kami.

However, with the stylus I can only draw free hand or use the box highlighter.
Free hand is great, but for annotating text I’d rather use the regular tools as usual.

Is there a way to use the stylus with the regular highlight/underline tool (ie, NOT free hand drawing over the text)?

Thank you
