How to setup facilities sub limits for each co.code

Hi Experts,

We have a business scenario, where company wants sub limits based company codes.

Scenario: Company has 10 million facility. we have co.codes-1000,2000,3000,4000. The co.code-1000 has 2 Million sub limit,co.code-2000 has 1.5M sublimit,co.code-3000 has 3M limits and co.code-4000 has 1 M limit. The remaining 2.5 M should be as it is.

Can we build this setup in facilities or treasury?Please let me know how to achieve it.

Thank you
