When you add documents to a Transmittal that are stored inside ProjectWise, it takes forever for the files to upload. Why is a file upload necessary? They are already stored on Bentley servers. If upload is necessary, do it on the backend, not on the client side. For large files it can take a long long time for files to upload.

I've had users in our org ask me if they're doing something wrong because it doesn't make sense that the documents need to be uploaded.
