Mass action on making variants

Hi,

I don't think that the mass actions system will help you with that.

Instead, do you know about the "copy" button on the products listing ?
Once you configured a product like you want, with the variants you want, you can select it on the listing and click on the copy button to generate a copy of it which will have the same variants configured the same way. Then, you can just change the name/code/price based on your needs in the copy and won't have the recreate the variants for it if they have to be configured the same way.
