Crossfilter data based on dynamic measure

[mb769]

For the staff, I calculate a 'Dynamic Age' measure, i.e. the age shown depends on the Year I am slicing (the date slicer):

DynamicAge = 
CALCULATE (DATEDIFF (MIN(Staff[DoB]),  MAX(Date[Date]), YEAR ))

This works perfectly.

I also categorise the staff in groups depending on their age. For this I have a measure

NumberOfStaffInGroup = 

CALCULATE (DISTINCTCOUNT(Staff[Staff_ID]), FILTER (Staff, [DynamicAge] <= MAX (Group[max]) && [DynamicAge] >= MIN (Group[min]))

which gives me the following chart (NumberOfStaffInGroup on Y-axis, Group on X-axis), next to a table with all staff members:

Now, I want to use the interactions, so that by clicking one of those bars, my table is sliced and shows only the staff members in the selected group.

Does anyone know a trick? Joining the agegroup table on a dynamicage measure does not seem to be possible.

Thanks!
