New type of task


Is it possible to add a new type of task in the gantt ?
I’m using all types of tasks but i want a new type that is like milestone but dosn’t have same properties and look like a red triangle.
This type of task is to have a look to project problems directly on the gantt

You can use CSS to draw a triangle instead of the rectangle:
