Removing base page slug from /ask page

I have installed anspress 2.3-beta2 on an empty wp. Created two pages with the anspress shortcode, one with slug “question”, and one with “home”, i have set home as the wp front page, and question as anspress base.

Now both url.com and url.com/question show the list of questions, and url.com/question/post-name show the question, that works fine. But the ask link (url.com/question/ask), shows a 404 error. If i change the base page slug to “questions” then url.com/questions/ask does open.

But i’d really prefer to have the ask page either on url.com/ask or url.com/question/ask

How could i achieve this?

I tried modifying the includes/rewrite.php file and removing $slug . from line 119 so it would look like:

$new_rules[ "ask/([^/]+)/?"] = "index.php?page_id=".$base_page_id."&ap_page=ask&parent=".$wp_rewrite->preg_index(1);

But the ask link still shows as question(s)/ask, and /ask only shows a 404, I tried saving both anspress options and wp permalinks to rebuild the rewrites but didn’t work.
