Option to make airport labels NOT disappear when approaching an airport

At this moment the airportname and distance labels from an airport in a flightplan, do disappear when one comes close to the airport. I suppose this is because most airports are clearly visible at the ‘disappear’ distance. However, if one flies small airstrips, the disappearing often happens before visual discovery of the airstrip.
Therefore, can there be made an of/off switch for the disappearing within a certain distance, or a slider with which the distance can be set to a shorter distance.
