Not without writing your own code. However, if the customers are getting back to the product pages (and if they aren't then make the message in the notification template more clear), then it's not really any great drama to alter the templates and make the download links as big and bold as you think you might need.
You can add a message right at the top of the template in huge letters if you want. Examine the part in the template where the download tab and tab content are and there'll be a test token section that determines whether a download is available. Use the same test section to add your own message elsewhere in the template.,
I'm assuming your order emails have the products linked up with the store pages.. make sure that is the case.
