On a specific deal part it is possible to attach a document i.e a loan agreement.
Open up the deal
Click on Attached Documents
The pop-up will show if there already are any attached documents, listing the documents.
Add (+), Remove (-) or download the attached documents.
It is possible to see if a deal has attached documents; the number of documents will be shown next to the Attached documents icon. A preview has also been implemented, so you do not need to download the document to view it.
