Reduce friction when straight and smart quotes occur in a paragraph

Let's talk about character dialog in our manuscripts. I've got quite a bit of dialog in an existing Markdown file and all of the dialog is surrounded by straight quotation marks. I'm using Dabble to make an edit so I copy and paste bits of the source material from the Markdown file into Dabble. So far so good.

Then I start to edit some of that dialog in a paragraph. Dabble types only smart quotes and will complain about mixing straight and smart quotes in that paragraph. And that's a good thing. So I have to manually go in and retype any straight quotes remaining in the paragraph. Meanwhile other paragraphs with just straight quotes will not be flagged.

This situation places a cognitive burden on the writer. It adds friction to the editing process. Is there a better way for Dabble to reduce that friction? Can Dabble be smarter about smart quotes? How about a button that floats beside an offending paragraph that will convert any dialog to use smart quotes?
