Would it be possible to create a script that removes individual items from the cart, with the current setup of Email Recommendations?

For the implementation of Email Recommendations, we are looking for a way to remove individual items from the cart. I am aware that there is a script provided by SFMC documentation to clear all items from the cart:

<script type="text/javascript">       
   _etmc.push(["setOrgId", "MID"]);       
   _etmc.push(["trackCart", { "clear_cart": true } ]);   
</script>

Unfortunately this does not fulfil the requirements.
