Unfortunately there is no such overview. The only way to make the life easier is to use some conventions. A good practice would be to create line-items with meaningful name like "Filter x" and use the "Filter x" as filter in the Saved view. By looking at the reference formulas you can see that a line-item is used in a filter.
For normal columns, you can add comments in the "Notes" that the line.item is used in saved views.
