bitcoind – How do I add more OP_RETURN output to PSBT transactions?

I would like to fund PSBT transactions made with Bitcoin Rust.

Since only the Creator can set the inputs and outputs, there doesn’t seem to be a function to do so.

There is an API with Bitcoin Core rpc called “walletcreatefundedpsbt”, but unfortunately it only accepts a single op_return data field.

oh my god?
