That's unfortunate. The 2 liter clause for Helsinki Airport through me off and gave me some hope, but no. That's just the total volume.

Now regarding lonkero: This spring, I sent a 24-pack of lonkero with a friend heading to the airport. He ended up checking his cabin bag and brought the 24 pack as his sole carry-on. The 24 pack went to the dreaded secondary inspection in security, but they did let it through despite a total volume of 7.92 liters. Bringing it onboard was no problem. It fit the dimensions, it weighed just around 8 kg and fit neatly in the overhead bin. The perfect carry on. Any tips on a 20x100 ml case for next time?
