Import / export activities (engagements)

Does anyone know when Hubspot will allow users to export engagements meaning the email messages, notes and image attachments? It should be an easy thing to include in an export as csv files and image exports and I feel since we are importing all of our proprietary emails in hubspot, we should be able to export them otherwise it seems suspicious.

Can someone give us a timeline on this? Because competitor SuiteCRM already has this option, but we don’t want to have to leave Hubspot…but don’t want to invest in this company if we don’t know if we will ever get all of our documents back… ETA please?
