Hi Oriolegd,
If the original part and separate part are two individual documents and you want to hyperlink from one of them to another one's bookmark, based on my test, there is no out-of-box solutions in Word 2016 for Mac. However, in Word for Windows, when we click Link>Existing File or Web Page>select another document>we can click Bookmark button to select the bookmark in another document. In Word 2016 for Mac there is no similar button to see all bookmarks in another document.
You may follow up this thread to see if our community members have some suggestions for your requirement with Word for Mac.
Regards,
Tim
