Mandatory importances to be available when using the 'Add Resource' feature in list view

We have recently enabled mandatory importances. However, many of our academics use the 'Add Resource' feature to add items to their lists. Unfortunately adding items in this way does not force an importance to be set, only a prompt at list publishing stage, which of course can be overridden. Therefore this greatly anticipated new feature will not have the impact for us that we had hoped. We would like mandatory importances to be available for all instances where items are added to lists.
