Hello,
that is a good idea, but the widget doesn’t have that feature at this time. To find a page with a certain CPT in a certain category, an filter further by special offers, that is only possible with search.
The widget feature is mean to give site owners an opportunity to provide an incentive of widget exposure for listing owners that create special offers by allowing site managers to give them the exposure in the widget.
It is possible to hide the ‘view all’ link with CSS.
Going further, Special offers can be exposed to advanced search. A search for the particular CPT, and filtered by special offers would then give you a URL that you could place in the sidebar with a button like ‘View all Special Offers from ____”.
