You can drag screens from the Project Explorer and drop them into the
storyboard to add them at the pointed location. You might want to
uncheck the "Link with Editor" option in Project Explorer (yellow
arrows), to avoid the storyboard file scrolling back into view
Let me know how this works for you.

I believe the problems I have described happens only on screenflow diagrams, that extend beyond 1 screen - I am sending a screen recording to email@example.com.
