TOC with Finsweet for multiple CMS items

Hi all,

Using Finsweet, is there any way to generate a table of contents based on a CMS’ Rich Text rendering multiple items on page?

So basically making a TOC of all the Collection’s Rich Text rendered on 1 single page, like a large Pillar page for SEO.

For me it won’t work, it says the Finsweet attribute contents was found twice on the page (because the CMS has 2 items, it places 2 Rich Texts on the page, giving the error).

Did anyone ever get this to work? Would be a real bummer if there is no support for this.
