Add the ability to tie two (or more) stats to a date in current (not historical) reporting

Report Builder is limited on the attributes it can take on a historical report; it's possible to use more attributes on a current mode. IBM Engineers often recommend the use of fields (like tags) when proving out a concept or supplementing the tool where the addition of a field has not yet matured. Good.

In our scenario, we use the tags field to distinguish certain artifacts where the category field cannot supply the information but there's no solid "an additional field should be this" option. For one such tag, we want to know the stats on how many artifacts were opened with that tag and how many were closed in any given month.

We CAN see the overall open artifacts and closed artifacts in a historical graph for some of the out of the box fields. It works well. We CANNOT use the tags field, even to filter down the artifacts going into this report.

In the current reports, we can use the tags field as a filter and get the accurate information for either/or but not both. This means we can filter on a tag and group by the creation date to see all the artifacts opened by month. However, if we want to see the comparison of artifacts that were closed in those same months with the same tag, we need to create a new report instead of adding this information to the report.

Please add the ability to group two or more artifacts by date in current reporting.
