Separate/Itemize Burden Types in Custom Reports

Currently, all types of burden are lumped together and reported as one number. It would be great to be able to report various burden types (e.g. Workers Comp) with separate accumulators for each type of account-specific burden created in Feature Settings > Time & Expenses.

Our specific application, I would like to record timecards to both active projects and a fictitious "Overhead" project to report indirect costs. It would be helpful to have the ability to report burden itemized/accumulated by account/type.
