P&L Custom Total Calculation/ Formating

Would like to ask for advise on the P&L - Budget vs Actual I need for our dashboard.

I need to show the bottom totals as "Total Cost of Goods Sold" (Income - Cost of Good Sold) and the total % of plan is (amount/budget amount).

is there anyway i can customize the bottom total? or can you suggest an alternative to get the calculations i need?

also, is it possible to show in 1 table the same information with the current month and year to date side-by-side?

thanks in advance.
