Selective Import/export in addition to global approach

[redkaffe]

In order to be able to do a selective Import, the actual way is to delete unwanted files from the exported Zip File. While this is working OK, it would be nice to be able to simply export/import a few manually selected items, for exmple when doing incremental setups of a Production Tenant from a Qualification One, items are generally incrementally copied to Production as they are rolled out progressively... deleteing files from export can be a bit cumbersome if the items are many...
