Community Tip - Did you get called away in the middle of writing a post? Don't worry you can find your unfinished post later in the Drafts section of your profile page. X
For example: There are two identical bolts on the illustration. How to create callouts for them with the same number? Now, each bolt has different number("1" and "2").
You can copy and paste the callout, when it asks if you want to renumber just say no.
