Item wise taxes and templates

Hi @umair,
Is this feature on the board to be introduced? Believe the same Github issue is open reflecting this - Add support for Item based Taxes and Charges · Issue #6270 · frappe/erpnext · GitHub

Would it not make sense to incorporate the below hierarchy?

Global Sales / Purchase Tax template

Item Master Tax > overrides Global Sales / Purchase Tax Template

Sales / Purchase Line Item Tax > overrides Item Master Tax

Example being here, some items need to use different tax codes if they are capital expenses compared to non-capital expenses. So in a purchase order there might be 10 of the same items with 2 items being capital purchases and the other 8 being non-capital.
How can this be achieved in the current setup?

Thanks
