TYPO3 Core

It is possible to assign single values from constants in setup like so:
lib.myextension.someconstantvalue = {$lib.myextension.someconstantvalue}

Usually there is more than one value that you want. For me this usually end up like that:

lib.myextension.constantvalues {
thisvalue = {$lib.myextension.thisvalue}
thatvalue = {$lib.myextension.thatvalue}
anothervalue = {$lib.myextension.anthoervalue}
}

I'd like to be able to just say:
libmyectension.constantvalues < {$lib.myextension}
