How to define the dynamic shortcuts for 2 main activities?

[cRuiTe]

in my app has multiple main activities.(use activity-alias to create 2 app icons on phone)
i want to define different dynamic shortcuts for each or specified.(default is only define for the app launcher activity)

the guidance in android homepage says: Only main activities—activities that handle the Intent.ACTION_MAIN action and the Intent.CATEGORY_LAUNCHER category—can have shortcuts. If an app has multiple main activities, you need to define the set of shortcuts for each activity.

but how?
