The elektron sequencer is not built for this, but it is a much-requested feature to add polyrhythms. Try using the arpeggiator on one track to create an opposing rhythm to your other 4/4 track by way of the arpeggiator’s odd time division.
I think it’s best to be happy with what it is rather than to focus on what it isn’t, but I understand your feelings.
You could also try using this information compiled by another member, but the answer is that there is no “easy button” approach to polyrhythms or odd time signatures with elektron gear.
You can always add a feature request to the digitone 2 feature request thread as well.
