How to add Atahualpa support to SEO data transporter plugin?

Hello,

I’m a longtime Atahualpa user and now I need to move my site to Catalyst. I have always used Atahualpa SEO and now I need to translate this SEO data to Catalyst. I was told to use SEO data transporter plugin but it doesn't support Atahualpa.
Catalyst support told me I could tweak the plugin to add atahualpa compatibility, I don know anything about coding but they sent me a piece of the plugin´s code and told me to find the atahualpa´s equivalent in plugin.php and add it:

'Catalyst' => array(
'Custom Doctitle' => '_catalyst_title',
'META Description' => '_catalyst_description',
'META Keywords' => '_catalyst_keywords',
'noindex' => '_catalyst_noindex',
'nofollow' => '_catalyst_nofollow',
'noarchive' => '_catalyst_noarchive'

I don't have any coding skills, any help will be appreciated.

Thank you for your time,
Luciano
