SharePoint integration

If I have a SharePoint list with items that are linked into a SharePoint library and I want to take the documents and transfer to TechDoc and replace with TechDoc links, is there a way to do this without having to go and replace individual TechDoc links in the SharePoint list? Maybe somehow get a report with TechDoc with links and use Quick edit in SharePoint, if I can match up the TechDoc Excel report with the SharePoint list? Just thinking there has to be a way to easily do this.
