Filtring

Hi,

I have a question.
Is it possible to filter shortcode? in meaning of what it displays when I call it in the code?

For example:
I put this in my code, so it displays the list of questions

<?php
echo $shortcode = do_shortcode(‘[dwqa-list-questions]’);
?>

and I would like it to automatically filter this shortcode so it displays only OPEN questions.
so when I open the page where it should be displayed it shows OPEN questions and nothing else.
