AIS protocol for radios

[Redlegvzv]

Intuitively, it seems that we should have a system whereby if an AIS vessel is highlighted on the MFD, that the radio should be able to transmit to the vessel using the MMSI number shown on the MFD as part of the AIS data. Is this feature in existence or in prospect? In practice it is impractical to try to program in a vessel's MMSI number "on the fly" while cruising, in order to make a digital call. In practice, one can, at best, simply obtain the AIS vessel's name from the AIS data and call it by name on channel 9. AIS is helpful for this (better to call by name than calling "sports cruiser off my port bow" but to be able to "click and call" on MMSI would be very desireable. Is this feature in existence or in prospect?
