can u add feature to auto calculate base rate if final price is given and option like inclusive / exclusive of tax is chosen ( like in quick books)

also another very useful feature is that it automatically selects CGST/SGST or IGST based on base place & supply place .. and in case it is intra-state, i just need to choose 'GST' rather that CGST/SGST and the app auto breaks up tax into 2 halves..
this is really very convenient for the workflow
