Yes, it is possible.
add following code in your theme’s (child theme’s if any) functions.php
add_filter( 'fep_filter_before_email_send', function( $content, $mgs ){
$content['headers']['reply-to'] = 'Reply-To: ' . fep_get_userdata( $mgs->mgs_author, 'user_email', 'id' );
return $content;
}, 10, 2 );
