How can I add more OP_RETURN outputs to a PSBT transaction?

I want to fund a PSBT transaction that I created with Bitcoin rust.

It looks like there is no such function to do that as the Creator is the only one that can set the inputs and outputs.

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

What can I do?

How to compute MAST commit bytes in bitcoin payment?

Image
The hash digests used to create the commitments are each 32 bytes, so proving that a spend of Figure 7-6 is authorized (using a merkle tree and the particular conditions) and authenticated (using signatures) uses 383 bytes. By comparison, the same spend without a merkle tree (i.e., providing all possible authorization conditions) uses 412 bytes. Can anyone explain how to compute 383 bytes and 412 bytes?
