Move subtasks from one project parent to another project parent

Question

I have a routine need to move a subtask from project X to project Y.  Based on what I've been able to determine the only way to do so is a multistep process.

1.Convert subtask to issue

2. Move issue from project X to project Y

3. Make issue a subtask of the new parent

* Is there an alternative that would allow this to be done in single step?
* Is there API REST calls that can make this easier? 
* Can those API calls become embedded into the UI?  Essentially, the only input required is the input of the new issue parent.

Odd that this it isn't possible to move a subtask to another project. To end-user subtask is just a ticket, nothing special. And the fact that it can be done in a roundabout way, convert subtask to task, then move to other project, than convert back to subtask, confirms that it is definitely possible. So then I'd expect a subtask to be moved between projects just like tasks and epics.

How can you still do it if your organization works on Task>subtask levels and Epic is not an available creation?

Thanks for you suggestion.  I agree with your suggestion of starting it at the issue level and then at least it can be moved between projects.
