I wish there was a toggle button for BULK/CHAT on each message I send or I wish
when I send a BULK message, it remains a BULK message the next time I send something to the same group.

I use BULK messages for my youth baseball team because I just want to broadcast messages about games/practice. Sometimes I have CHAT on because of other text messages, and then when I go to send another BULK message, it ends up sending a CHAT message.
