Batch/Bulk adding images to one item

Is it possible to batch add images to a single record in Omeka Classic? Currently, I use the Dropbox plugin to batch add items, but a single record is created for each file. I’d like to find a way to speed up adding images to a single record without having to do it manually.

Thanks for any assistance!

Dropbox also adds itself to the Files tab of the Item add/edit form; here you can select multiple files from the dropbox to be added to a single item.
