It would be helpful and better document control if you could upload a document, plan sheet, photo, etc. when the RFI is answered, in lieu of having to answer the RFI then upload it after the fact. Being able to upload it along with the answer will allow for better documentation showing the end user that this particular document was a response/answer to the RFI instead of it possibly being confused with supporting documents for the original question. PlanGrid offers this function but it was not transferred into Build.
