Not the answer you're looking for, but still...

In most cases, you should not merge coverage from unit and integration tests.

The value of unit tests is that they improve the design of your application and ensure that corner cases of your code is working correctly. You should try to have a high branch coverage of your unit tests.

The value of your integration tests is that they ensure that the main use cases of your application are working correctly and that the whole stack is integrated correctly. You should try to have a high functional coverage for your integration tests. (But it is fairly hard to measure functional coverage with a tool).

If you need integration tests to improve your branch coverage, that's a strong indication that you should review the design of your code. And if you already have a high branch coverage without integration tests, adding them should not modify significantly your metrics.

Feel free to down vote this answer as it is a bit of topic and fairly opinionated...
