Deleting a Category, Sub Category, Even if it's Attached to an Item

When deleting a Category, Sub Category, Modifier etc, it would be helpful to have the option to delete it even if it's attached to a item. 

At the moment we're not allowed as we get the message:

We're are then forced to try to find which item, modifier, modifier group, sub category is attached to which one, then delete or de-select that option to then go back and delete the original option

- Can we have a button that pops up next to the note on the screen that says "Still Delete?" or something like that, and then it will unattached the items to be reattached at a later time
