Report builder: MIN & MAX aggregation for date fields

Hej  Gainsight community,

I am surprised that I cannot us a MIN or MAX aggregation on date fields when using the report builder. 

Maybe I am just unable to find out how it actually works, or no one else needs such a aggregation on data fields when building reports & dashboards. But I would really appreciate to have such an option.

Please, dear GainSight peeps let me know if there is a work around or, in case this is really not possible, if you have planed to add this function.

Best regards,
Max
