Suggestion: Work load tracking of the axes

I have been using the machine for a few days now and noticed that axes are having different work loads (Z being the least used). Thus I am wondering if the program can track the work load on each axes (this requires unique ID of a axis) and then over time give advise for rotating the axes position. A great advantage of this design is the interchangeable of the axes so in this way the machine will wear out evenly.
