create a Invoice with 2 or more outputs (+change)

[skeutmeier]

I would like to see a feature, so that I can create an Invoice though the API, but split the outputs to 2 or more wallets.

Imagine a Shop where you want to publicly traceable donate a percentage of your sales for a good cause. Like 10% of every payment made is directly sent to the wallet of good cause.

Another use case would be a external provider that offers a service and can be paid a fee, directly, on every purchase.
I would really like to see that feature.

The way blockchain works we can't make users send to multiple addresses at once, so it's the postprocessing step. You can use payouts feature for that
