Split pallet functionality - sell in multiple UOM (package and pallet)

Hi.
How do I sell different units of same product. I have one product but want to sell it as SKU1- 1 package, SKU2 = 10 packages, SKU3 = 1 pallet. Order comes in on different units but deducted from one stock.

We will produce as pallet units (=50 packages) and be able to sell as pallet or single packages.
I’m asking for some type of split pallet functionality.
