recently, i learn [branch development], pega suggests create a branch development application(set the main application as built-on application),then create branch,and check rules to branch to update...

This action will avoid affecting the main application and so it does.

But the development application doesn't have main application's case types.

What if i want to run case type in development application to check branch rules,and switch to main application to run again to check main application rules are not affected by development application's branch ?
