Getting Dynamic Item Page to also include a repeater showcasing items from the same Collection

I’m having trouble with getting a repeater within my dynamic item page to showcase other items from the same collection.

For context, I’m working with wix studio.

Specific example:

I have a collection storing all my tours.
And I have a repeater showcasing brief information about each tour that I use throughout the website. I call this the product widget. And they have worked perfectly for other pages using dataset filter to showcase whatever tours that are relevant .

Except when on the dynamic individual tour page. This is a page that has more detailed info about one specific tour. But I also want to use the same product widget (repeater) setup to showcase several tours in the same city.

However, when I deploy the same setup, the repeater only shows this specific tour. It seem to have an auto filter, because the filter section has this default message already “shows items based on their URL” - this message does not appear in other dynamic pages which are not from the same collection.

And I basically cannot get it to showcase any other item. Can someone explain the logic behind this, and also any workaround?

Thank you!

Attempted Solution
I have tried adding a column (multi-reference field) in each item that calls back to the same table (I call it “Related Tours” and values are basically other tour items/objects), but this does not work.

From what you explained, it sounds like you might be using the dataset that creates the dynamic page to try to showcase other items besides what is on the page.

So as an example, if you have two tours (A & B), the dataset that created the dynamic page is filtering to show the content related only to A or B.

To show content from the dataset other content not related to the item, add a second dataset to the dynamic page and filter it to show content that is not and use another dataset referencing the dataset that created the dynamic page depending on what fields are completely unique to each.

As an example, I used the preset and you can see on the Full Name 01, the repeater at the bottom shows everyone except Full Name 01.
