# Link Reference Set Editor with SNOMED CT View

There's another approach to Simple type Reference Set authoring, that allows context-sensitive selection of members from the SNOMED CT hierarchy.

Users can ![](https://content.gitbook.com/content/N7ynFOLTw3W9Zow9AaAJ/blobs/zJqJUynlbzTEvPOOmUjN/611027019%20\(2\)%20\(2\)%20\(2\)%20\(4\)%20\(4\).png) *Link active simple type reference set with view*, and the members of the active Reference Set are highlighted in the SNOMED CT navigator with black fonts. Concepts that are not members of the Reference Set are greyed out. A number is appended to the Preferred Term, which indicates the number of subtypes the concept has which are also members of the attached Reference Set.

Adding a new member is as easy as navigating in the hierarchy and right-clicking on the appropriate concept. Removing a member from the Reference Set removes the highlighting from the tree.

This method helps to identify potential new content, that is semantically close to already existing members but was skipped from previous versions of the Reference Set.
