Remove Default "Sunday AM" for Service/Day Submission

Would it be possible to remove the default "Sunday AM" selection from the Service/Day field on a new sermon submission? I think it would cause fewer issues if it were left blank. We just reportedly had five consecutive "Sunday AM" services in Eureka, according to our AC Central submissions. :) While not difficult to edit, and certainly the result of user error, it seems like it would be less likely to occur if the field was nominally blank. A blank (or "select") would probably stand out more readily as incomplete than a default "Sunday AM". We will continue to try to raise awareness of this in the sound booth, but it could also be helpful if it were possible to change the default selection. Thanks.
