Need a provision to keep "In Plan/budget" items in CT DMA

We in tax get few items during our Business planning exercise which then further should be added in CT DMA as draft items. These items should have the capability to hold budget figures in them so when an idea is changed to a demand then we can keep a track of originally planned budget vs required budget (via solution plan or project estimate).

We have the capability to add the items in the draft state in Idea module via Bulk upload functionality but we don't have the ability to add the funds to those items.

May be there can be another way to tackle this requirement so happy to discuss it with CT DMA development team.
