Hi PhilthyCollins,
As I mentioned when I replied to another of your recent forum threads, we do not currently offer an option that would allow you to enable the “Optional eBay Gallery Images” setting as part of the CSV upload. Similarly, we also do not offer any functionality that would allow you to enable this setting in bulk from your Saved Listings page.
I do not know of a way to specifically select a Promotional Shipping Rule in bulk (or from a CSV file) either, but I will let our Product Management team know that is something you would like to see made possible with a future site update as well.
