How do I add a custom subtask I created to a project?

Question

I want to add an additional subtask selection when creating child issues for various stories. For example, some subtasks are related to development, others are related to the design team. I have successfully created the new subtask (see image below), but when I try and add it to parent issue, I still only get the default subtask option. How do I add the new Subtask Issue I created so it appears on ALL projects? I've been losing my mind here.

Yes, team-managed projects don't use schemes for their configuration.

Also, they only support one sub-task type at the moment, called "sub-task"
