Calling child workflows of another task queue

Is your feature request related to a problem? Please describe

No.

Describe the behaviour you'd like

I'd like to be able to define the task queue of a child workflow. It's already available for activity calls, but there isn't a taskQueue param for child workflows.

Describe alternatives you've considered

I've considered using an activity that can run in the desired task queue and make it call the child workflow there.

Additional context

The solution above seem to work, but since I couldn't find any explicit guidelines on this (I've seen a similar discussion here, but it was related to external workflows), I thought it would be worth opening the issue. Let me know if that's an explicit design decision. I'd be willing to implement this if it makes sense.
