4-3 Odd Leo Personnel

In the 4-3 Odd Leo formation the stock personnel for some reason doesn't actually use 3 Linebackers like a 4-3 defense should. The stand up player on the left of screen (outside shoulder of the Left Tackle) is REDG when there's already DT1/NT/DT2/LEDG on the field. 

If possible, could we either get this player defaulted to the SAM instead or install a "SAM Edge" package to substitute the SAM into that specific position being that the MIKE & WILL are already on the field.
