Can we load project cost with user defined exchange rates through FBDI

Hello Everyone,

As a part of projects cost data conversion, we are trying to load the month on month historical project cost from project inception to date.

For the projects where ledger currency is different than project currency, we would like to load the cost with exact exchange rates relevant to corresponding transaction date. So is there a way to load the historical cost with exact conversion rate of prior periods by providing relevant exchange rate or raw cost in project currency, ledger currency etc directly in FBDI, instead of defining the exchange rates for prior dates in rate type and using that rate type in FBDI?
