I would guess no because you will need to set a field based on the button and then promote it so the workflow can create a condition based on it.
Maybe you can edit the out-of-box in SharePoint Designer, but it's so easy to just create a reusable workflow that does the same thing, I'd go that option.
Maybe the best option is to use our QdTask workflow XTP - I'm attaching it. No code required and no workflow either (although you can add).
Take a look at the lab. You can easily add the XML Template Part to your form and configure to create tasks based on it.
