template file (.tpl.php) for a specific mailchimp campaign

Issue Summary

Hi,

i created a custom content-type (newsletter) which consist of a description block and several articles in teaser mode (title, image, body trimmed) and successfully send this campaign to the mailchimp template. The problem is all the data in my content-type, is displayed in the content section (#std_content00) of template. Is there any way to display different part of my content-type in different blocks of campaign template rather than content section? I mean is it possible to create a template file (.tpl.php) specifically for my customized mailchimp template?

appreciate any help.
