How can we change the settings to allow a minimum of 1 attendee?  See the example below.

I'm traveling alone and am automatically entered as the attendee.  Our settings don't allow us to submit the report until another is added so we are currently adding a Dummy Attendee as the other attendee and submitting the report.

There has to be a setting where I can make a certain expense type allow a single attendee or more.  We do have other expense categories that must require multiple attendees (Business Meals etc.).  Is it just 1 setting and it's all or nothing?   It's a ridiculous workaround.
