Yes.
In the PWP page editor, go to the page where you want to place the link.
Type the text you want to use for the link (text you want the person to click on).
Select that text (drag over it).
Click the link icon (the one that looks sort of like links in a chain).
In the panel that comes up, enter the complete link URL (what they would have need to copy and paste).
Save the connection, and save and publish the page.
Check that it works when accessed through a web browser. You may need to refresh the page.
