<dtml-call "REQUEST.PARENTS.append(FileLibrary)">
would do it, but would be *VERY* hacky code.
Instead:
Give your method a parameter, say "sourcefolder".
In your method:
<dtml_in "(_.has_key('sourcefolder') and sourcefolder or
PARENT[0]).objectValues('File')">
(You may want to factor the "(_.has_key....PARENT[0])" out.)
Then, when your method should use a special folder, use:
<dtml-let sourcefolder=whatever>
<dtml-var FileLibrary>
</dtml-let>
