Hi John,
the defaulthomepage is configured in the Site administration. That works in the official Moodle Mobile app too.
As for the other question, unfortunately our core team do not have the resources here to help people use the open source code version to build custom apps. We provide a service where we can customise the app for anyone who needs it including the Push notifications (Airnotifier) service management. This service helps fund the improvement of the app in general: https://moodle.com/mobileapp/
Kind regards,
Dani
