Bulk add single image to multiple products

I have a WIX store with hundreds of new items per week that I upload using a bulk product upload csv. (and take off the old from the previous week.) I have image URL’s for all of the items I am uploading… but not all are active or final images at the time I am need to get the new products up.

There are two things I would like to be able to do and don’t think there’s a way but maybe some of you have ideas:
(1) Change a setting to have these image links refresh in a way other than re-uploading the same CSV again

(2) Have a way to bulk add my own customized placeholder-type image to multiple selected items at once. I can do it one at a time, but it’s soooo repetitive and usually about 40 per week so not completely undoable but just annoying and I feel like there should be a way.

I feel for the first part you could try using Automations and running Velo code to update the images.

If you wanted to check through the documentation, you could check here: Velo Wix Stores Backend Introduction | Velo

For the second one, I would probably use export/import CSVs to reduce the time as the updating the CSV would be easier to update rather than doing so via dashboard.
