sub task workflows

Question

hello
i have created an issue as new feature,this issue follow a workflow,for example
Specs Writing->Acknowledge>Testing->QA
i have created a 4 sub task for this issue 
1-Specs Writing who follow another workflows
open->in progress->Done
2-Acknowledge who follow another workflows
open->in progress->Done
3-Testing who follow another workflows
open->in progress->Done
4-QA who follow another workflows
open->in progress->Done
my questions are:
if i put the issue type as new feature,can i create automatically 4 sub tasks for the issues?
can i locked the sub tasks while the first didn't finish yet ?i.e i cant put acknowledge in progress while the Specs writing is not done ?
and when i finish from specs writing(statues done) the main issue go automatically to acknowledge?

Best Regards 
Rita

You can have multiple sub task workflows, so the first part of your questions is a yes.

You can use the post/pre functions on the main issue to hide the transition step to the next workflow and have that dependant on the outcome of the subtask to follow the flow of work you are suggesting.
