how do I make the FROM box on a bulk email show the same list as a single email?
I guess the "Allow mail from logged in contact" option is for sending Email Activity or Contribution receipt but not bulk emails. Might be because if the bulk emails are not send using site domain address than it end ups in users spam box. 

Its a good idea to raise for a feature request on https://lab.civicrm.org/ or you can implement an extension to include logged in users id.
