We will use "Notes and Attachments" in Opportunity record to upload some documents. Those documents are related to Electricity supplies (e.g. Id card, last copy of bill etc). Is there a "clever" way to organize them and have a "file" structure there? Because an Opportunity could include multiple notes & attachments for each supply and i want to have it organized in order to be easier for the user. As far as i know, there is not such capability, but i ask in case somebody has found a clever idea.
The only way i am thinking of is to write an Apex Trigger to validate the filename has a specific format. Any more ideas?
