OSGI Workflow: Send email with attachments

I have a use case where I need to send 1 or more attachments with an email.  The current email component seems to allow for 1 or more attachments but, not dynamically.  The attachments are in a payload folder and I don't know how many until runtime.  This is an attempt to find the equivalent component to Livecycle's "Send with attachments".  

Can I point the attachments to a "payload" folder?  

Thank you,
