How to split transactional emails and notifications?

Hi everyone,

I am currently using FluentCommunity, FluentAuth, and FluentSMTP.

In FluentSMTP, I have already configured two different Email Providers. I am trying to achieve the following setup for better security and delivery management:

1. Provider 1: Handles user registration, verification links, and security codes (FluentAuth/WordPress core system emails).
2. Provider 2: Handles daily notifications, digests, and newsletter emails.

However, I cannot find any settings to split these routing paths:

• Inside FluentCommunity, there is only an option to select a single "From" email/sender.
• Inside FluentAuth, there is no setting at all to configure a specific sender or email routing.

Right now, everything goes through the same default provider. Does anyone have a good workaround, a code snippet, or advice on how to route such emails to different providers?

Thanks in advance for your help!
