FSX Enroute control zones and ATC radio frequencies

[Panxua]

Hello,
A PlanG regular user, I would like to know if my favourite planner could show Enroute ATC radio frequencies.
When in a transcontinental trip, in IFR mode, you are directed to the next center by the current center at the time of changing zone.
Such zones are of course displayed on the screen, and when you pass your mouse on the limit, you get the information relating to the name of the zone.
The virtual controller is giving you the radio frequency of the next ATC zone.
It should therefore be possible that such indication be accessible on the map itself.
Would it be possible that such function be included in a future version ?

The interest is of course that you could prepare on your radio set, as a stanby frequency, the next one, and have just to push the button to get contact with the next controller.

Thank you for your answer.

Have nice flights.
