Coverge with BDD scenarios

We are using BDD scenarios in our .net project along with unit tests. 

Is  it possible to capture metrics given a set of scenarios , how much code has been covered. FOr ex with 5 features, coverage is about 80%. This is kind of similar to but different than unit test as well. 

Second is there a value in capturing this metric as unit test provides coverage for any new blocks that got added.
