This would be very helpful for nurture drip campaigns in workflows. Sometimes someone mets a goal of a workflow, sales reaches out, and they are not ready to buy but still want to receive our awesome content.
I’m admittedly suprised this isn’t a feature yet - it would be awesome if the feature could be added. We can already see contacts in action if you have a delay set in the workflow -- having the ability to add people there would be a quick win?
