Sorry for John (Erazo) for overlooking the need to avoid case sensitivity.
You already have a great solution.
This handler can modify a input property if it find one and assign a new
property and value (if new value provided).
Hope it's hopeful.
on modifyProp pList, oldProp, newProp, propValue
if not ilk(pList, #propList) then exit
if voidP(oldProp) or voidP(newProp) then exit
if voidP(pList[oldProp]) then exit
if voidP(propValue) then propValue = pList[oldProp]
pList.deleteProp(oldProp)
pList[newProp] = propValue
end
