Keep history with rightsholder instead of the most recent entry only
We would like to see a history of the communications with the rightsholder. Right now, we can only upload one document, which makes it difficult in those situations where Publisher A says "we don't own it" and sends us to Publisher B. We can only upload the final email for Publisher B. The next time we ask permission for the item, the item still says Publisher A, but our records say Publisher B. We can add notes, but they are not searchable, and then we have to recreate the process all over again. Having the ability to upload multiple documents means we can retrace that conversation. We also have some publishers that send us both a contract and an invoice. We would like to upload both so we can compare the two and have a record of whether the invoice was received.
