If it is a post then it will delete the post.

How can I do a S&R but select which in the list to apply to?

What do you mean by select in the list?

Say I do S&R

A post as 5 instances.
I want to click Y/N to each of those 5 in that 1 post.

Ok. I’m not sure what you mean by that but you can click the delete button on whichever post you want.
