Is there a way to sign multiple messages at once?

I am wondering if there is a way to sign multiple messages at once with ts sdk. For instance, with the multicall method, I am able to execute multiple transactions at once. Is it also possible for signing?

Sorry this has taken so long to get to! We’re just going through old feature requests.

Recently we added a way of adding multiple witnesses to a transaction, but this was using the hashed transaction rather than an arbitrary message. Could you please expand a bit on what your expected use case would be? A single account signing multiple messages? Or multiple accounts signing a single message etc?
