Show Linked Tasks

I have some projects that have an complex connection of tasks that call other tasks, and sometimes this spans across multiple projects.

So just like you have the "Show Linked Projects" action on each task, I would like a similar action that shows which other tasks are calling the selected task (i.e. tasks that call this task from the "Perform Task" action). 

You could call this "Show Linked Tasks". :)

I know this can be done from the search option by entering the name of the task, but this is cumbersome and shows a whole lot of other noise than I want to see.
