Dear vremruata,
Your suggestion is valued. We would definitely look at adding it but it may not be possible to do in the near future. In the interim, you can ICICI credit card to avail the EMI in case you have one.
In case of any account related issues, you can contact our Customer Support through any of the following channels -
