how to get clip slot id number

I would like to have a small max audio effect at each single clipslot. This patch should give me these two values ($1 and $2):
path live live_set tracks $1 clip_slots $2

The track ID number I can easily trace it using this patch:

but I am still trying to figure out how to get the ID number of the clip slot...
