Learner Activity Filter to Include Unscheduled Activities

For reports where the 'last learner activity date' or 'last scheduled learner activity date' can be used as filters could we please include unscheduled activities in these. Sometimes learners may have an unscheduled activity added against their profile and it's not necessarily that eLearning activities are the only activities a learner undertakes.

The Class Enrolment Activity Hours report pulls data from unschedueld activities which means the report engine is able to identify this data.
