This should come pretty close to what you want.
The logic is easy enough once you realise that the level-numbering
is available, independent from section-names.

sub custom_title_hook {
    my ($i,$A,$return) = (0,'0','');			#initialise variables
    my @sects = split (/_/, $packed_curr_sec_id);	#get level numbers 
    while ($A eq 0) { $A = shift @sects }; 		#discard leading 0s
    while ($i < 4) {
	$return .= &fAlph($A);			#convert number to letter
	$A = shift @sects;			#get next level
	++$i;					#increment counter
    }
    $return					#should be 4 letters
}


This hasn't been tested.
I hope it works OK.


Hope this helps,
