My CA demands that the invoices under RCM in GST regime should have the following details. How can i modify RCM invoices?

1) Heading "expense voucher" should be replaced by "Invoice"

2) our GSTIN should be displayed

3) CGST and SGST bifurcation should be displayed (currently somehow the print of RCM invoice doesnt display and tax)

4) invoice should also display "GST payable/paid under RCM"
