Is There A "create Quick Product" Add-On Or Feature?

It seems there are many steps needed to create a product, and many times these options and steps are needed to create a simple product. Is there a simplified way to create products? Most of our vendors are selling t-shirts. Ideally, we can have a easy made template for t-shirts where the only information the vendor needs to add is; images, price, description, and inventory for each size. Ideally, the vendor could add all of this one simple "add product" page and then publish the product.

We want to make it easy and simple as possible for the vendor to add products.

I am afraid, only to options are available at the moment

- Import

- Bulk product addition
