Need assistance editing a custom Ribbon in word

Job ID: 31478947

Budget: $30 – $250 AUD

We have an existing old ribbon in word,( I do not have any knowledge about how it was set up or how it functions) with buttons pointing to sharepoint for templates.
I need one button adjusted (it currently points to an old network drive and asks to rename the document ) I want this button name changed from new report to Default template and pointed to a location in sharepoint like the others.
