Simple issue.

I have two email accounts on my Mail app for windows 8.1. one is gmail, second is a company mail.
The thing is i want only one of those accounts to sent mail (company)

Right now it automatically responds from the account the mail was delivered to. Is there a way (i know the program is pretty damn primitive) to change a defalut sender?. So the email program would disregard where the email was delivered to and only send from one previously chosen account?

Hope there is a way to do so.

Ps. I know i can always click "more" and change send email from the other account, but as i write 60mails a day i wont be able to click it every time without going crazy after 24h.
