Inform editor when deleting a page if other pages use its body text etc. Existing or new function?

Hi,

There is a function in Episerver that informs an editor that he's about to delete a page that other pages link to. Is there also a function that informs the editor if he's about to delete a page whose body text etc some other page gets/uses (dynamic function)?

If there is no such function, how can I create one?

Thank you!
