I'm not talking about sending multiple ops in one ... @QuipTalk

Yes, sending multiple transactions in the same block is possible. Depending on your use case, you could use a Tezos wallet to send multiple transactions in a single block. For example, if you are sending funds to multiple people, you could use a wallet to send x tez to A wallet and y tez to B wallet in the same block. This would make the process of sending funds more efficient and secure, as all of your transactions would be included in the same block. Additionally, if you are working with a larger number of transactions, you could look into batch operations, which allow multiple operations to be included in a single transaction.

Do you have a use case for this in mind?

Don't understand. You can send x tez to A wallet and y tez to B wallet in the same block. Isn't that you want to do?
