When an email comes to a group address, how can I reply from another address (in g suite gmail)?

I have my g suite gmail account set up like this:

  • default from address: foo@bar.com
  • quux@qux.com is a google group
  • when sending from baz@qux.com, reply-to is quux@qux.com, so the quux group receive the reply, but the email appears to come from the person Baz

Now when I reply to emails to quux@qux.com, I would like gmail to preselect baz@qux.com as the from address. i know i can configure it to do that for emails to baz@qux.com but how to do it for emails to quux@qux.com?
