Connect Multi-Reference to Drop Down Input

I have a Dynamic list page and want a drop down input to link to a multi-reference column; the drop down will be used to filter the dynamic list. The items in the list go to unique dynamic pages.

According to the article drop downs and multi-references should be able to link together: https://support.wix.com/en/article/about-user-input-elements

I found a workaround to link the drop downs to the tags, but this is very clunky.

Does anyone have information on how to link the dropdown inputs to the dynamic lists multi-references? Is this even possible?
