Ability to send sms to multiple recipients at once

Some gateways have an ability to send sms to multiple recipients at once. It makes sense when you have to send a hundred or a thousand of messages, so you make just one API call instead of a hundred or a thousand.
Is it possible to extend core to gateways API to check if the gateway supports multiple recipients? And obviously add corresponding function to the smsframework, something like sms_send_multiple() which will check that ability and will fall back to the multiple sms_send() calls if the gateway doesn't support multiple recipients?
