Distribution List - Create

I have read the previous posts on creating distribution lists and while there are workarounds to creating a distribution list from a list of emails they are inconvenient and not how people work.

There are occasions when I would like to create an email to a group of people, who I DO NOT want in my contacts - a temporary project group, a select group of clients, a bunch of employees I am firing (just kidding), etc.

I such cases, creating a custom Contact list and then a distribution list from it is a waste of time and grossly inconvenient.

May I respectfully ask that you add the (trivial) capability of a distribution list to simply be a container of email addresses, with the option to create it by pasting in the list (comma, tab or \r, \n\r separated)?
