Hiding Sold Products from the Main Store page but displaying it in a separate Sold section

Dear All

I have built my first Square Space website and have found online help here fantastic, with a solution to all my specific customisations and requirements except for the following, so was hoping someone might be able to suggest how to set this up or give a work around or some custom code.

I wish to have the main store page display all my items except items tagged with the category 'Sold.' Then for there to be a second page (or Menu) with the title - Sold, that then the displays all the 'Sold' items and excludes all the items for sale. Or ideally instead of having a separate menu as currently setup, I would be really happy if it could be done within the main shop, so no items tagged 'Sold' are listed until you click on the 'Sold' Tag Shortlist button (currently hidden) then all the fro sale items will disappear.

At the moment it is set up kind of how I want it but all the sold items are still listed in the shop for sale. I've successfully hidden the sold Menu Tag from the shortlisting menu. I then tried hiding the sold tagged items which solves the problem for the main Shop page but then the items of course disappear from the Sold page. I had though I might be able to have two Shop pages using the same products and then setup different display rules for each but this doesn't seem possible.

The site is https://www.halexhorns.com and the password - Kruspe

It would be amazing if any one has any thoughts how I can achieve either of my planned layouts.

Thanks J
