Rollover CPEs should include any group A CPEs earned in the last 6 months of your previous cycle that were above the required amount (120 for CISSP), but only up to a maximum of the suggested annual amount (40 for CISSP). This is defined in the CPE handbook.
Based on that criteria, you can hopefully work out which ones were rolled over when looking through your previous cycle's transcript in the CPE portal.
However, I agree, it would be nice to see it officially broken down and not just rolled up into a single entry.
