FS Items - period specific setting??

Hi Exports,

We have requirement which is version dependent;

In a version we have 24 FS Itmes used, Now our client want to make 10 FS Items Quarterly submission & the remaining 14 FS Items Monthly. And we use "flexi upload" to upload the transaction data in to BCS. We use "Delete all" Method & Cumulative values will be uploaded into system.

When we upload cumulative data for 14 monthly FS Items; The other 10 FS Items(Quarterly) Values are getting negated to Zero.

This is specific to project but what I am looking at is "Is there any setting which can make an FS Items Period specific"

Please let me know if any clarification or information required.

Your help will be very much appreciated.

Thanks
