batch layer visibility for selected instances?

As part of my workflow I am often changing the layer visibility options on some (but not all) instances of the same object. I was looking at the batch_layer_visibility script by crazypanda and it almost does what I need, but it can only change every instance without finer control. Does anyone know of another existing script where you could either select just the objects you want to change, or apply the change to a specific range of pages? Or know how to modify this one to do this/have tips on how I could do it? I have some baseline scripting knowledge but I haven't made anything for indesign before. here's a link to the one I'm using now. Thanks!
