When creating a client list, it would be very helpful to have the ability to choose "ALL," and then check of which clients to include, instead of having to list each one individually. It would also save time if we could pull from the established Groups in order to create a list.
Also, having the ability to list off clients individually and hitting "Tab" in order to get to the next line would save a lot of time, as currently the user needs to click on the arrow down button to add a new line.
