add routing enteries from an external file to Click configuration file

hi,

My question may sound primitive, but I couldn't find any answer for it so
far,  Does anyone know if it is possible to add my routing entries to click
configuration file from an external file ?

For example for RadixIPLookup( ) click element, so instead of adding all
the entries between the brackets, how I can tell the element to read them
from a file ?

Thanks

Ahmed
