Custom 'No events returned for this query' string

A lot of the lists generated on my site are through either the PHP function eme_get_events_list or the shortcode [events_list], both usually used in conjunction with the categories parameter to retrieve a list of a particular kind of event.

These lists refer to quite different types of ‘events’ – in my case exhibitions, and open calls for submissions – and I would like to be able to return a different string for each one if eme_get_events_list or [events_list] returns 0 events for the parameters provided. Currently if either of those returns 0 events, nothing is displayed.

Is this a possibility for a future version?
