View Item Dependencies - What is Dependent upon a given item/subitem

We would like to see items/subitems that are dependent upon a given item represented in a way that we can view them when looking at a specific item/subitem. E.g. When we look at item A, we want to be able to see that items F, S, T, Z are all dependent upon item A. Perhaps this is a feature add to the existing dependency column or it’s a new column. The info/logic already exists in the database as the connection is there and visible on a Gantt chart - this however is not a usable means for managing changes to our large projects.
So, again we want to see at the item/subitem which other items/subitems are dependent upon that item - this is in addition to current visibility to see what item/subitem that given item/subitem is dependent on. We need to know that by changing item A we are creating downstream impacts that should be evaluated before simply changing the timing on item A.
