Ok my answer to the first post. I didnt manage to just duplicate content-top-a-b-c.
But what you can achieve easily is to add a position "Extra" without that abc.
open in the template-folder
html/layouts/body_mainbody.php
or
html/layouts/orderedbody_mainbody.php
that depends on wich file is used in the index.php of the template.
<?php echo $gantry->displayMainbody
or
<?php echo $gantry->displayOrderedMainbody ...
after
<?php if (isset($fparams->contentTop)) : ?>
<div id="rt-content-top">
<?php echo $fparams->contentTop; ?>
<div class="clear"></div>
</div>
<?php endif; ?>
add
<?php /** Begin Extra **/ if ($gantry->countModules('extra')) : ?>
<?php echo $gantry->displayModules('extra','basic','standard'); ?>
<?php /** End Extra **/ endif; ?>
in templateDetails.xml add the position
<position>extra</position>
Now you can add a module to that position.
But as I said you don't have the a/b/c option for this ...
