Restricting the same collection list being called twice on the same page

Hi all!

I searched Webflow university for a solution for this, but I didn’t come across anything in the filtering or sorting sections of Collection lists… so here goes.

I have a CMS collection for Testimonials with about 10 items in it. I have three calls to this CMS on the page. One for the Hero Image, and the other two are for some preview sections below it.

What I’d like to do is to make sure that what’s being called in each section is unique. The problem is that I can’t find a way to filter either the hero CMS call to limit what’s shown in the preview area and vice versa. I’m using three different collection list wrappers that all use the same CMS.

Is there a better way to do it?

Attached is a screenshot of what I’m talking about. The prep page is here:

Thanks in advance for any attention or advice you can give with this.
