So I googled around and searched the forums but didn't find anything explicit.
I got this from some BIP related wiki:
bitcoin:R-175tWpb8K1S7NmH4Zx6rewF9WQrcZv245W?amount=0.567&label=book&req-aal=1tZdShH7b38klseWrTZm5sE8PrtZPwqdK:0.123:game&message=Thank%20You
and it doesn't work.
Is there any way to make URIs that would fill in a transaction that has many outputs?
