Hi kmanek
Feature you are requesting is not provided by module itself, it requires to modify code and add custom url for new links added, you can try to modify these 2 files:
/templates/ja_aiga/acm/hero/tmpl/ style-2.php and style-2.xml
style-2.xml
<field name="btn-link-2" type="text" default="" size="40" label="HERO_BUTTOM_LINK_LABEL" description="HERO_BUTTOM_LINK_DESC" />
<field name="btn-link-3" type="text" default="" size="40" label="HERO_BUTTOM_LINK_LABEL" description="HERO_BUTTOM_LINK_DESC" />
style-2.php
<?php if($helper->get('btn-link-2')) : ?>
<div class="btn-action-2">
<a class="btn btn-<?php echo $helper->get('btn-type'); ?>" href="<?php echo $helper->get('btn-link-2'); ?>"><?php echo $helper->get('btn-title') ?>
</a>
</div>
<?php endif ; ?>
<?php if($helper->get('btn-link-3')) : ?>
<div class="btn-action-3">
<a class="btn btn-<?php echo $helper->get('btn-type'); ?>" href="<?php echo $helper->get('btn-link-3'); ?>"><?php echo $helper->get('btn-title') ?>
</a>
</div>
<?php endif ; ?>
