Co-Agents should have access to properties in DigiSign

We recently discovered that Co-Listing and Co-Selling agents do not have access to properties in DigiSign. In order to DigiSign a document and have it go back to the listing/transaction associated with the property they have to go to the listing or transaction, upload the document, then select it and choose to DigiSign it. This is a much longer method than should be necessary. It seems like an oversight that these properties don't show up in DigiSign. Why have incomplete access to a property?
