You would have to read the policy and see what and how it covers the individual buildings. Blanket policies are usually not divided by the number of buildings to determine individual building coverage, like a RCBAP.
If the policy does not contain the "compliance aid" statement, then you are going to have to make the determination as to whether or not the policy meets the requirements of 12 CFR 208.25(b)(9) or your regulator's corresponding regulation. If it meets the requirements of that section, you must accept it. If it does not, then you could still accept it, if it meets 208.25(b)(3)(iii).
With the July 1, 2019 deadline approaching on these new requirements, the last thing you really want to do is accept the policy now and be faced with rejecting it at the time of the next policy renewal.
