Hi @kevzhu
Good question.

Hey there, @kevzhu! Great question and we definitely appreciate ya reaching out.
I did some digging and you’re right, “Start Date” isn’t currently supported at the moment for the “Create/Update Card” Actions in Trello.
That said, it is an open feature request that I went ahead and added your vote to! While this doesn’t guarantee implementation it will allow us to track and gauge interest. We’ll also email you if and when that changes as well as update this topic.
Thanks again for sharing your feedback and welcome to the Community!
