[NTG-context] Is there a syntax for making many index entry's all in one?

I am using \index{} to populate \placeindex (an index) with items. I am wondering if there is any syntax that allows one \index{} command to define more than one entry, for example, something like this: \index{presidents+Lincoln, Abraham; Lincoln, Abraham} The result is two appearances in the index: LLincoln, Abraham Ppresidents    Lincoln, Abraham Is there some syntax for making this possible, without calling \index{} multiple times? --Joel
