[Plugin: RSVPmaker] Shortcode question

I’m hoping to get the following shortcode to work:
[rsvpmaker_upcoming type="next-event" no_events="We're still planning our next meeting. Please check back soon for updates!]
Is there a way to show upcoming events for a certain category, but then have a customized message if there are no events in that category?
