Supplier Liability Account based on capital / expense spending

 Hi

We have a legal requirement to have separate liability accounts for suppliers based on the nature of spend i.e. Liability Account for Capital Expenditure and Liability Account for Expense Items. Same supplier can provide capital as well as expense items. What is the best way to capture the spending in resepective liability account based on the nature of spending? Is there any standard functionality which can be used or do we need SLA to be changed to achieve this requirement?

Thanks.
