Is it possible to access platformio.ini configuration in the local env without its name?


Let us say we have the following platformio.ini:

platform = espressif8266
board = esp01_1m
framework = arduino
build_flags =

monitor_speed = 115200

Is it possible to access monitor_speed and assign it to a build_flag DSERIAL_BAUD_RATE without extracting monitor_speed to another [section]? or without stating explicitly in which section it lives as long as it is in the same section in which I want to access it? Accessing it like this does not work ${monitor_speed}.
