This for Bridge to support custom metadata for batch editing

This for Bridge to support custom metadata for batch editing. Currently, Bridge only sees IPTC data, but when I used a custom metadata editor, it only adds it data fields in the raw imbedded sidecar. My pain point is that I have to enter each field individually, and cannot batch process this step. The DAM our company uses does take advantage of the custom fields, but there's no way on bridge to even view the custom fields since it only sees IPTC related fields. Many of our images have different fields for retail SKUs and other identifiers on a spreadsheet. I like to have 1, a custom data field viewer of the files. and 2, to have a way to batch edit the metadata by having bridge look at a CSV file and preload the fields based on matching the columns B to fill out all of the columns with all of row 1 data once there's a singular match. Typically a UPC code or SKU number.
