XF 1.5 Change report textbox to a dropdown menu?

With the current setup there is this for reporting which isn't bad but then again people won't know what to report it as most of the time.

Is there anyway to make it a drop down menu instead like this for reporting

If I take the textbox out and leave just the drop down menu when you select a reason and click report it says you must enter a valid message.

Any ideas how to make it work?
