Get & Apply signatures #1245

I want to use bitcoinjs-lib and build a system like bip-0174 https://github.com/bitcoin/bips/blob/973a303edc2cc7a9cc84f3fc84673e606aef68f3/bip-0174.mediawiki@Responsibilities

Where am getting stuck is the signing part. Is there a way to sign the transaction and get the signature. Then later apply that signature to the transaction. The Bitcore API provided that functionality, but I can't find how to do it with bitcoinjs-lib https://bitcore.io/api/lib/transaction#multisig-transactions

Nope. There is no currently supported method for "Get Signature" or "Apply Signature"

PSBT support will likely be added in the future.
