Sadly, while Asana provides a lot of really great features. They don’t have a published road-map so we aren’t really able to guess when something along the lines of what you’re suggesting will exist.
Based on your level of experience, I’d really recommend Zapier then. You could get away with what you want using their drag/drop builder without doing any coding. It just might take you a day or so to figure it all out.
Let me know if you’re really struggling and I can try and point you in the right direction on the platform.
