Exclude Glossary Terms Not Used

[GrantPierce]

My team has a universal glossary that we use for all of our projects. Our projects are all PDF outputs. I want the glossary proxy to auto detect the terms within a TOC and ONLY list the terms it finds... without having to condition the terms. The goal is to not go through each project to find which glossary terms are used and which ones are not - I want this step to be automated.

Example:

Glossary Terms include- Fish, Dog, Rabbit

Only Fish is found in the particular project, so the project output only defines "Fish" in the glossary list.

Thanks in advance.
