I am interested to create a custom value for the maniphest.statuses called "Blocked". The purpose of this status is to reduce clutter on my Maniphest list and my project workboard. Visually, they should be striked-out.

Note that the value of "open" should be true because if it's "closed" then it will disappear in my project workboard.

Now is there a way to introduce custom formatting of tasks in Maniphest list and project workboards such that they can appear striked out in both places?
