Enable/Disable Push Notifications After Initial Prompt

Hi,

Once Push Notifications are configured via App Studio, the user usually gets an initial prompt asking whether to Enable/Disable push notifications on the device upon the first login. However, during subsequent logins this prompt does not appear. Is there a way to let the user disable/enable push notifications on the device after the initial prompt/login (preferrably as an option from within the app)?

thanks,

Hemal
