Ignore test results from collection.bru in report

[wobl9]

Hi!
I want to tests screen with pagination. There are some tests that are identical for each first page. And for second all tests are unique.
I decided to put all tests for first page in collection.bru. It works perfect, but I they also run for second page. I tried to do something like:
if (firstPage) { return } else { runTest }
It works, but in tests report there are a lot of useless green tests.
Is it possible not to run tests from collection.bru by some condition?
