Assuming there are models called "Index0" to "Index10", does this work or at least take the effect?
a = 2; b = a + 3; SetThingModel(Index0[a + b]);
What was necessary for the above question to work?
(Lacking what will make the above question not to work?)
Do you think you can put cog verbs within "[" "]" brackets to concatenate as variables rather than just letters or numbers?
