Also if you look at SA 995, clause 5.1.6 Additional requirements provides the option of specifying additional requirements such as PREN.
I would suggest, if reporting PREN is mandatory as per the project specifications, then go back to the supplier, with the request for an amended MTR. It may cost you some dollars/euros, but would prevent hassles down the road.
Also I would feel the the content of the following article, though informative could be beneficial..
Thanks.
