title: CRM 2011 - New Appointment from Case defaults Required Attendees to Account
body: <p>When I create a new appointment from the context of a saved incident it defaults the "Required Attendees" field to the incident's account. I want it to default to blank or the current user. (To create the appointment I used the navigation pane on the incident to view related activities then use the ribbon button add new activity.)</p>
  
  <p>Where can I control that behaviour?</p>
  
  <p>I tried looking at the entity mappings but it appears there isn't a "mappable" relationship for the "RequiredAttendees" field. (I checked as per the instructions here: <a href="http://rc.crm.dynamics.com/rc/2011/en-us/on-prem/5.0/help/ui_cust_Mapping.htm" rel="nofollow">http://rc.crm.dynamics.com/rc/2011/en-us/on-prem/5.0/help/ui_cust_Mapping.htm</a>) Have I missed something or is this a hardcoded CRM-ism?</p>
  
  <p>Going forward do I have any options to modify this? I suppose I could do javascript on form load but I'd prefer this be configurable inside CRM without touching javascript.</p>
