GenoProX will have the ability to display
satellites objects which are labels or pictures capable to display some data of another object. What is interesting about satellites objects is they follow the main object, so the move together when moving the primary object. One solution is having the date as a satellite text label, however this will be too much work for you for every individual having a date. Perhaps one solution is having a move where all dates displayed are displayed in a special format with an optional additional calendar, such as Hebrew.
Let me think about something that will be easy to use yet reliable.
