I need to configure an app that has the ability to take multiple pictures at each point and label pictures depending on what they are about. Currently in ArcGIS Online, attachments are named based on their order and quantity: "Photo 1.jpg". Is there a way to have the labeling scheme be based on a drop down?

The photo/video labeling syntax I need is listed in this chart. Each point will need most or all these pictures, and assigning an order is not an option since many of the photos depends on what is in the field.
Alternatively, is there a way to have multiple attachment fields? All my blob fields did not publish successfully.
