Insert an active but variable hyperlink from the DataSource in a MailMerge Word doc

Hello,

How do you insert an active but variable hyperlink from the DataSource in a mail merge Word (2013) document?

For example, suppose you are doing a Word mail merge and have defined, as you're DataSource, an Excel file (named Source.xlsm) which contains several hundred records (rows). Also, suppose that the 6th column in the Excel file has the heading URL and contains several dozen different URLs distributed randomly throughout the records.

When the mail merge Word doc is created, the URL for a given record appears wherever the <<URL>> field is placed. However, it appears as simple text just like the rest of the document and does not have any hyperlink functionality.

Questions:

1) In a Word mailmerge, how do you create a <<URL>> field which has hyperlink functionality?

2) Is there a way to display a "friendly name" (using the term from the Excel =HYPERLINK() function) as the hyperlink in a mailmerge rather than the URL itself? (For this question, assume that the 5th column [in the Excel file used in the above example] has the heading "URL Name" and contains the "friendly names" for each record.)

Thanks
