ARI Batch Channel Commands?

In conference applications, we need to mute/unmute groups of callers, and to move groups of callers between bridges in a Stasis application. At present this involves locking the Stasis application until multiple ARI calls have been despatched and returned. Is there a faster way to do this, for example using the Dialplan or a different interface? If not, might it be an idea to add batch channel/bridge commands to ARI to reduce the application traffic to the Asterisk box?

Thank you
