Customise Twilio sender address

We would like the ability to customise the sender field when sending via Twilio. For example, we would like to send out some messages with our Company Name as the sender rather than the phone number.

For Twilio this is a matter of setting the From field on the API to the text entered. I've checked this by calling the API directly, using the Twilio account that we have connected to Front.

I believe that you are currently setting the From field to the selected phone number, we would like the ability to override that value and set it to a piece of text.
