Another workaround for those on Anniversary Edition of Windows 10, which, as a Surface owner, you should definitely get anyways. Open up Sketchpad in Windows Ink Workspace. You can edit your pen buttons so it immediately opens that screen. Draw what you want, then you can crop to the size of your drawing, and COPY it. Then you just paste into your desired note. While the previous workaround allows for further edits, this has helped me to create figures to go along with my notes. Though the previous workaround was indeed better for note-taking. I hope this helps, at least until Evernote officially supports a similar feature.
