Filtering collection by a current page

Hi all

I am trying to filter a collection list by the current page (which is from a different collection list).

For example

  • a collection of paintings has a data field for Artist which is also a collection.
  • when on the Artist Page, I want to show a list of Paintings done by that artist.

At the moment I tried creating the (Painting) Collection list on the Artist page and filtering by Artist Field…but there’s no option to select the CURRENT ARTIST
