Ad-hoc Clinics

Would it be possible to automatically show Ad-hoc clinics to the Show All, Day View instead of having to tick the extra practitioner running the ad-hoc clinic that day? For an example please see our diary for Monday 6th May - Isabelle Killiana is running an ad-hoc clinic to provide cover for Georgina who is on holiday but unless we remember to tick Isabelle manually her clinic does not show in the default view therefore we are at risk of not filling her clinic that day
