Even/Odd flight level for airway segment

It’s an old post, but is the only one I found asking for this information in charts. I know that Simbrief seems to give the right FL for the airways, but it would be nice to have this information on the charts (properities of the airway segemnt where it shows airspace, fixes etc.)

We shall use your suggestion for potential enhancements and new functionality. So, please be as detailed as you can.

Only one issue per thread so that others can easily see what has been reported.

It would be nice to add even/odd information for airway segments in segment info dialog. It helps to plan the flight manually. Nowadays it shows the airspace, distance and altitude limits. It would be nice to add EVEN, ODD or BOTH flight levels.
