Nesting Shorcodes

I’d like to have the download monitor plugin control the look of the link that shows inline after the email is submitted. Is there any way to use nested shortcodes by leveraging do_shortcode($content) to call up the [download] shortcode for the download monitor? I’d like the download box template (seen here) to pop up.

Thanks for the great plug-in!
