Manage products in Shopperpress

I’m using the Prosperent products importer with Shopperpress. Unfortunately, there is no way to update the products once they’re in your store… I will therefore have to manually delete them and re-import them every now and then to ensure that they are still available and to update the prices….

Does anyone have experience with this plugin? If so, how do you manage to update the products? Is there a way within wordpress to segregate certain products, delete them quickly?

Thanks for your help!
