How to stop system from calculating burdened amount for project budgets?

When setting up a project budget, if the resource being budgeted is enabled for burdening then the system calculates the burdened amount for the budget using the burden multiplier. This is causing issues in budgeting as well as reconciliation. The burden configuration is enabled t to create separate item for burden row therefore it would make sense to budget separately for that expenditure type(where the burden will be stored) than bump up the amount of raw cost on the base resource. Any ideas on how to stop system from calculating the burdened amount on budgets?
