How to link the folder / navigation button to a different page?

Hi all.
Due to brine only allowing categories and not sub categories. I decided to make a folder on the navigation that has several shops within it, so that they look like categories even though I guess they are actually separate shops. - this is fine and works quite well when you hover over the shop button and select the relevant option from the dropdown.
However, if you don't hover over the drop down and you just click on shop itself, it just brings up the first shop of the several within the folder.

I wondered if there is a way to either link it to another page, or stop it linking to anything at all until you follow the drop down?
I would love it to go to an 'all products' page, but because I have my products technically in separate shops I am guessing there is no way to do that? i.e it would be all of shop 1 or all of shop 2.
Hopefully that makes sense.
Thanks in advance if anyone has any suggestions!
