Is there a feature in Mailwizz similar to a plugin in IEM called Multiple SMTP

I understand that Mailwizz campaigns can select as many SMTPs as we want for each campaign. However, it seems that their not really in parallel. The campaign just changes SMTP when a particular limit is reached.
My question is, is there a feature or plugin for Mailwizz that acts like Mobarak's Multiple SMTP that will allow us to use multiple SMTPs that will actually speed up sending (SMTPs run in parallel per campaign)?

Thanks in advance for the clarification.
