Exclude element from copy across all Collection Pages


Is there a way to exclude 1 element from copying across all CMS Collection Pages (1 collection)?

For instance, I’d like to add a slider to a portfolio page and for it to be different on every Portfolio page - so sometimes it is a slider, and sometimes a video.

Right now I have 6 pages and if I insert and edit a slider on 1 Portfolio page from the same CMS collection (not in the collection editor, but in a normal page editor), it automatically creates THE SAME slider across all 6 pages with the SAME images.

I was wondering if I could exclude this one element so I can edit it manually on each page?

Thank you!!
