Hi @Emanuel_Teljemo,
I can cconfirm this function has never existed in Asana natively. Apart from the workarounds and third party tools mentioned by @Bastien_Siebman (in this post @Phil_Seeman who developed Flowsana explains how you can achieve this with his tool) I don’t believe there is currently a way to do this. I’m not an API expert, but hopefully @Phil_Seeman or @Bastien_Siebman can answer this question!
If you haven’t yet, I’d recommend upvoting Forms: Ability to have questions trigger a task/subtask creation & option to share/manipulate at form level
