Is there a way to show newsletter subject as post title?

Hello!

we’ve configured this plugin on our website to have an archive with our past newsletter. But we realized that the newsletter subject is missed out. Instead, post title of the newsletter (https://startup.gal/newsletter/newsletter-13-2020-30-03-2020/) is the mailchimp name of the newsletter.

Is there a way to show newsletter subject as post title?

Thank you in advance!
