That's fine - just create the appropriate pad templates, and then
implement the request pad function for your request pad template.

No way to give advice about that - we don't know anything about your
element. But there's nothing intrinsically difficult about what you've
described - just push data on the pads you have!

I mean do we need two _chain functions or we can push data to the 2 pads in the same _chain function (the data push to the 2 pads is different).
