AWS Chatbot - Meaningful Event Rule Messages

I am currently trying to get my chatbot set up with some event rules. The specific rule I am working with right now is a Cloudformation Stack Status change. I am able to get my event rule filter set up, and I can get the rule to publish to the Chatbot's SNS topic successfully.

However, the message that I get in slack is pretty much useless. It supplies the "Cloud Formation Stack Status Change" event name, my region, account number and the stack that was changed. But it provides no status....

So on a deployment I just get 3 identical messages saying that the status has changed for that stack.

The main issue is that in events you can have input transformation before the event message is sent to another resource. But AWS Chatbot doesn't have the ability to accept input transformed messages. I don't really understand the point of having this pipeline of information if you can't modify the message to give you the info you actually care about.

I was wanting to know if there is a way to achieve what I am trying to do. And was also wondering if there are any plans to update chatbot to accept these transformed messages.
