Imagine a scenario where I send an envelope to several recipients containing some documents (let's call this the "first batch"). Later, I send a new document inside this same envelope. If any recipient hasn't completed signing the documents in the first batch, the new document is sent to them as usual. They receive an email notification, and upon opening it, they can view both the documents from the first batch and the new one. However, another recipient who had already completed all the pending signatures for the documents in the first batch isn't sent this second notification with the new file. I'm developing this functionality in PHP with the eSignatureAPI + e-sign client sdk.

I'd like to know if it's possible to create this functionality. And if so, how can I do it?
