We need the ability to map to Electronic Collection. Because you cannot map to E-Collection, you have to have a separate profile for each collection for which you want to load portfolios. This dramatically increases the number of profiles we need to maintain. In addition, this requires more staff to have the ability to modify import profiles, even though the only thing changing each time is the collection name.

Mapping either the collection name (exact match) or the collection ID would be sufficient. This will enable more uniform loading of records.
