Managing Capital Flag at Expenditure Level

Hello All - we have a scenario where expenditures are entered for the same Task which is enabled as Capitalizable task. But business want to enter expense and capital expenditures against the same task how to achieve this uncheck capitalizable flag for expense expenditures ( we want to control capitalizable flag at expenditure level). We are using Fusion Cloud Projects (SaaS).

In R12 we managed this at expenditure level using capitalization extension, as ll extensions are not available in Fusion Cloud Saas we can't this option.

Thanks
