Until you can select existing contacts that have already been loaded to run through the lead enrichment process, the new Lead tool is useless to me. I have previously added my contacts over time (with or without full enrichment), what I want to do now is run the contacts that do not have email addresses (or bounced email addresses) through your lead enrichment process. There is no easy way to do this, the only option I see is to export those leads into a CSV that exactly matches your SDAI-approved CSV format and re-import it, that is a real pain and not worth my time. Please add a feature where you can select existing contacts and run them through enrichment for people like me, where my existing contact dataset needs enrichment, not new leads.
