Hi There is a ticket scheduled for Camel 3.0 to allow enrich and pollEnrich to support "dynamic uris" like the recipient list can do.
Though implementing this requires an API change and thus scheduled for 3.0. You can always use a java bean to consume from an dynamic computed endpoint. For example using consumer template etc. For ftp endpoints you may want to set disconnect=true, to avoid having the connection running for a longer period.
