Deleting emails from same sender

I am trying to delete large numbers of emails from same sender. I can see that you can sort be sender and then you highlight and delete the block. However, is there away for the emails just to fall under the sender on one line (so it appears once)?

Then I can just delete that one sender, and all the emails from that sender also go. It is a feature on Microsoft Office Email.

Hoping this can be done.

Thanks.
