I asked ages ago about this, and was told by admin that no, it isn’t possible to change what was shown there. Mine all used to be older items which I didn’t really feel showed the contents of my shop to it’s best, so I got around it like this:
I chose one of the items in ‘other shop items’ I didn’t want there anymore, and copied the listing (on the dashboard in ‘listings’, there is a copy button on the far right of each listing)
I then went to the original copy of that item and edited it to become a whole new item, I had plenty of new stock that needed listing so was able to do a few in one go.
That way, it looks like a new item on ‘other shop items’ but is actuallly the same url as the old item, which there is now a new copy of - does that make sense?!
The only disadvantage is that obviously if that old item you’re replacing had favourites on it then they don’t get transferred to the copied listing. And you have to take into account when looking at view figures that it used to be a different item so you might not get a very accurate idea of views for the new item.
I hope this makes sense to someone, I explained it as best I could! x x
