Nope, but it is possible. You would have to check the $CGI->{toggle},
and if it is present and is a toplevel entry, delete the
$Scratch->{memo} structure entirely. This would have to
happen above the tree call. I think this would work:
[if cgi toggle]
[calc]
my $par = '[data table=tree col=parent_fld key="[cgi toggle]"]';
delete $Scratch->{memo} if $par eq 'TOP';
return;
[/calc]
[/if]
