Can Ponni Boiled Rice be used to make idli / dosa batter?

[ABCD]

I bought a bag of Ponni Boiled Rice by mistake (instead of Ponni Idli rice) and even opened the bag. Can I use Ponni Boiled rice to make a common batter (in an Ultra wet grinder) for both idli and dosa ? If so, please let me know the ratio of boiled rice / urad daal.

Also, what is the difference between Ponni boiled rice and Ponni Idli rice?

Thank you very much.
