Incremental expression layer name when layer is duplicated

I'm using an attractor (layer from Null A to B) type setup:-

this:

linear(effect("Slider Control")("Slider"), 0, 100, thisComp.layer("Attract 06").transform.position, thisComp.layer("06").transform.position)

The layer naem is 

Is there a way that i can link the layer name (which is Attract 06) to the expression "thisComp.layer("Attract 60") entry, it would save me quite a bit of double clicking and typing as i'll be going into triple figures with duplications. maybe a dynamic link or some kind of exprression link?

? i'm all ears
