I'm about to create a new nurture campaign with an Engagement Program.
Some of the content we want to share was already sent to some leads in various programs (old nurturing, content gated, event follow up...)
Is there anyway to exclude some leads from a content when the content is part of a stream?
For example, my stream is sending content A, B and C.
My lead already received content B from a previous campaign. I want this lead to remain in the stream and receive content A and C but not content B.
