Add option to remove or keep the Contents box when exporting a page from a template as a PDF

Currently, a Simple Page, Encyclopedia, Article, Meeting notes page template includes a Contents box (a TOC). When exporting such a page as a PDF, you are given the option to include a TOC, you include it, but then, the Contents box in the exported file will also be included, causing a duplication in this way.

Would it be possible to include an option when exporting such a page type (coming from a template including a Contents box) to remove or keep the Contents box?
