Would it be possible to collapse automatically if there is no data in attribute?

Would it be possible to make an option to collapse automatically if there are only "empty" rows/cols inside an attribute under some other attribute?

Currently all those "empty" subtotals are visible and they give no additional information. The goal would be that only subtotals with row/col information would be expanded.

This would mean collapsing automatically those items where under the "Level1" attribute, in the "Level2" attribute, the only row/col is called "-empty-", "null", "-", or similar. In this case, after automatical collapse only "Level1" subtotal would be visible, because there is no additional information below that level.
