Now that EBPs can have multiple external event sources (by group), we need to update our user documentation to make this clear to users.

ATs:

• Documentation explains what is/is not selectable as sources for event based process
• Explains when suggestions are toggle-able
• Explains what can be used for autogeneration (only single source of ALL external events)
• Explains that existing event based processes are unaffected
• Explains that event based processes treat groups case-sensitively (it has always done this anyway)
• Screenshots are updated to reflect this change
