Managing/Blocking who can complete a task

Hi everyone!

I don’t know if this is able or not, hope you have a suggestion!

Recently, the purchasing and supplier department want to create a “make a request project” and leave behind the old system because asana works so well with multiple users and collaboration.
However we want to make a subtask that ONLY the general accountant can complete. Is there a way we can block who complete a task?
Because we want that the user creates a new task with the request and when the process is complete, our manager could just authorize the purchase right there.

Hope you can help! Thank you in advance!
