Add Link Reference To Response
A link is meant to be used by responses. A response can either use a new link or refer to an existing global one.
To refer to an existing global link within a response, click the top-right menu within the response editor, then select Refer to Global Link.
From the prompting dialog, select the link to refer to then hit Finish.
A new link UI appears within the group Links at the bottom of the response contaning the newly added link reference.
