Proportion based price for composite product

hi, could someone help me with a dynamic price issue?

I would like the following functionality for a composite product, the price of each individual products should be based on how many products are added to a composite product, meaning if I have one product it will be 100% price of the product added, if I have two products the price for both products should be half of their original price, for three products the price of each product should be third of their original price and so on.

Please let me know if there is an option I missed, or a plugin to achieve this, or what custom code would do this?

Thank you!
