Bonita application and custom event listener for pages

Hello. I am trying to create bonita application and cant realy understand 2 moments with it.

1) Is there any way to separete bonita application with bonita portal? I want to have "stand alone" application with its own authorisation, without default bonita portal authorisation page. The main idea to prevent users from access to bonita portal pages and functionality to create application wich would look like production application.

2) Is there any way to implement custom event listeners for bonita pages? For example, i want to call some function on table element selection / before submit button onclick event / or basicly any other event on page. Is there any way to include additional javascript for bonita pages for custom logic implementation?
