We want the ability to renew the contracts in bulk, not only one by one. The renewal options should add the 'CPI increase renewal option'. Once the finance team puts the new rate one time per year, that rate would be locked. The idea is that all the clients that are on the option of CPI increase for the renewal, we renew them in bulk instead of doing it manually one by one.
I would say both rollovers/renewals as well as bulk updates (e.g. ticket prices changes and they dont always fit perfectly into escalation logic)
