Hi Aniket. Thank you for your interest on this!
Yes, I decided to post the same question on the Ansys Developer forum which I didn't know about before yesterday to be honest. 
I am still trying to understand how to make the filter work on my own but no success up to now. If you manage to find some more references about the XML tag and how to generate a callback to it, please share them with me if you are allowed.
Yesterday I managed to access 'nCode DesignLife' XML file and I noticed they used the same tag in that extension, so there's clearly a way to do it, just haven't found out how.
