I would use a slightly different workflow to get the hyperlinks in faster.

Open a Windows File Explorer window and navigate to the folder with the PDFs in it. Position this window off to the side so that you can see both the Word document and the PDF in File Explorer. Now in File Explorer, Right Click and Drag the pdf into the Word window and let go where you want the hyperlink to appear. A mini-dialog will appear and you can choose "Create Hyperlink here"

The real speed boost comes when you select multiple PDFs in File Explorer and do the same Right Click and Drag. This gives you multiple hyperlinks in a single action.
