Make Gmail ask for "from" address with multiple inbox account

Question

I use my personal Gmail domain account to consolidate four (4) other accounts, two (2) of them work accounts.

I know there is a way to select the "From" address when composing a new mail, but how do I make Gmail ask or prompt me so I don't ever accidentally leave the wrong address set?

Answer 1

No, but I believe when you reply to a message it sets the To: field accordingly.

This is done when the
"Reply from the same address the message was sent to"
is checked in Settings > Accounts and Import
