Chord Tone in Numeric Value

So I thought I saw this option but I can't find it. Pretty much, lets say you enter in a bunch of (ctnr+k) chords with a voicing/and or melody underneath it. Is there a plugin that can tell you the numeric value (kind of like note names) of each note compared to the chord? If not how would I make it

Thanks in advance

Example: So If I enter G7 and the voicing underneath is F, B, Eb and Ab, by the noteheads it would say b7, 3, b13, and b9
