I've got a complex approval process with 6 layers of approvals in forms 10. I am looking for three things:

One: Can I allow people to add documents to a process without allowing them to delete documents? (alternatively, can workflow add documents to a process?)

Two: Can I access process A's variables and attached documents from Process B?

Third: Can I delete old documents from forms, so that the form data and/or attachments are not there anymore? (This is also a compliance issue)
