We have a subset of customers (opportunities) we want to start remarketing to once they meet certain criteria. As far as I know Marketo only stores and deals with leads. Is there a built in way to store opportunities in Marketo? My workaround was to just import them as leads (coming from our CRM) and add some type of true/false boolean field to the leads that will flag them as an opportunity or being part of this subset we want to remarket to. Then our marketing team can just create a list of leads with that value set to true and take it over from there. But if there is some predefined functionality for this already built in to Marketo I would prefer to do that.
