Best option to store rent price

[lamualfa]

Coming from Medusa v2, very glad Vendure is more flexible & understandable to overcome my specific use-cases. Thanks!!!

There're 2 fields I need to store:

1. rentPrice is contains price of each hour when user want to rent the product (Related entities: ProductVariantPrice).
2. rentHours is contains how many hours user want to rent the product (Related entities: Order & OrderLine).

After reading the documentation and understanding the reviews-plugin, I figure it out there are 2 possible options to use custom pricing when user wants to rent the product instead of buying it.

First Option: Add Custom Fields To ProductVariantPrice Entity

config.customFields.ProductVariantPrice.push({
  name: 'rentPrice',
  type: 'int',
})

The downside of this option is I can't utilize the @Money decorator to handle the monetary value.

Second Option: Create a Custom Entity Like ProductVariantRentPrice To Store The Rent Price

The downside of this option is I need to manually extend the ProductVariantPrice Entity directly from the product-variant-price.entity.ts and keep it up to date to the source.

So which option is the most suitable for this case? Or any other recommended option to solve this case?
