I am not sure what this means. What is a “leading argument”? Can you please
show an example? With my testing, nothing is grouped (unless one uses named
arguments, which of course go into that Map):
===
1052 ocs /tmp> <q.groovy
def foo(Map m=null, a, b, c) {
println "m:$m a:$a b:$b c:$c"
}
foo('Hi', 'there', '!')
1053 ocs /tmp> /usr/local/groovy-4.0.25/bin/groovy q
m:null a:Hi b:there c:!
1054 ocs /tmp>
===

Unless you limit your code by CompileStatic, that's technically impossible,
since normally caller does not (need to) know the signature of the receiver
until actually called.
All the best,
