Cosmos-Scope Measuring PRBS eye diagram jitter

In sandwork, we easily measure prbs pattern jitter with eye diagram.
However, can we measure the eye opening and jitter in cosmos-scope?

I tried this before.
But it only works for clock pattern. For PRBS pattern, it will report fake result. All data based spacing will be viewed as jitter too.
