Ability to create and send SMS campaigns through the mobile app

Good morning! Let me start by saying I LOVE your services! Suggestion is that I wish the app was more user friendly and had more capabilities. We are using your platform for church ministry communications-sending texts is easy and a quick way for us to communicate, however, we currently have to do all the SMS. sending from a desktop as the app does not support it. I wish there was an easier and quicker way to send text messages while on the go.
