Hey @anon80648536,
That‘s not possible directly.
However you can work with rules to automatically create tasks and subtasks. For the rule trigger you can even create trigger combinations. So for example all tasks added to section B with the custom field selection ABC will trigger subtasks 1-4 to be created and assigned.
You can even assign due dates, etc
I recommend trying that out.
Also here is feedback request thread that might be interesting.
I hope that helps.
