To insert details of budget

Hi,

We have implement static budget. But we are noticed that this module/session only captured total amount by ledger,dimension and period.
we can't insert the details of the budget. For example:

Ledger A1, Period 1: Total budget is $10,000.
Details as below (Things to insert)
Item L1 = $5,000
Item L2 = $1,000
Item L3 = $4,000

So we in current LN, we can insert the ledger, period with total budget for that only. Can't insert the details or insert Item L1, Item L2 and Item L3.

Do you any idea how i can insert the details of the budget for that ledger and for that period?

Your advice is much appreciated.
Tq.
