Query on pre-emi

I have a question on Pre-EMI. I understood from various forums that Pre-EMI interest can be claimed in 5 equal parts post completion of house construction. I would like to know if this Pre-EMI interest can be claimed on top of 2L interest? For Example: 5L Pre-EMI would be divided into 5 equal parts which means 1 lakh can be claimed after completion of construction. From next year onwards, I will be paying emi interest of more than 2L. So in an AY, can I claim interest of 2 lakhs + 1 lakh from Pre-EMI. Or would this be within cap of 2 lakhs. Kindly suggest
