Could I create a such Workflow?

Question

I have project, which contains of 3 app versions (teams): Backend, iOS, Android.

I need to create a next workflow: Manager creates issue (task) for Backend with 2 sub-tasks: 1 for Android and 1 for iOS. When Backend team finished a task and changed status to "Ready for Frontend" need to display these 2 sub-tasks on boards. Till this moments these sub-tasks need to be unvisible on iOS and Android boards.

I think option 2 may work. An additional option may be creating 2 subtask with a private security level and than changing security level to public when parent issue status transition to "Ready for Frontend".

To keep an issue off a board completely, you have two options -

*  Works all the time - Change the board filter so that it excludes issues that should not be there
* If the reason is the status of the issue, unmap the status from any columns

I'm not sure you can do exactly what you describe though - I don't think you can build a filter for "parent issue is now in status X", or script something that says "change status of subtasks when parent changes"
