chain planer binding

[Shard O'Glase]

unlike planar ally, planar binding has a target and not an effect.

I don't think I'd let it in but could you chain the planar binding spells,(lesser has one target the higher ones get one or more tagets).

I don't see why you couldn't it would just be more work getting all the baddies to cooperate.
