REST API creating new products workflow

[JustJohn]

Is my understanding correct that to create a new produc with combinations via REST API you must do things in this order:

1. POST simple product and retrieve its ID
2. POST all necessary combinations referencing the product's ID
3. GET product and retrieve the IDs of all stock_availables for that product
4. Map stock_availables IDs to combinations IDs
5. PUT stock_availables with the required stock quantities
6. POST images

Can it be shortened somehow? That's... well, a lot of separate requests just to create a single product. I at least know you can't POST stock_availables which could've made it easier.
