Need easy way to determine zap channels assigned

Is there an easy way to see what zap channels are assigned to what extensions? Having to physically click through dozens of extensions is tedious.

We have 96 channels on Rhino and PCI boards. We operate a multi-tenant environment so we connect and disconnect lines a lot and are always looking for free fxs zap channels.

you can have a look at the bulk extensions module in the contributed directory though I don’t know of hand if it supports zap extensions, but it might.
