My example following does not do precisely what you request;
but it covers the basic idea using two different Headers (rather
than subject line marker) to place the files into either of
three locations beneath MAIL_DIR_PATH:
zhighspam (high scoring spam "catch" user directory)
zspammail (lower scoring spam "catch" user directory)
username (directory for each user
In each case the file name is constructed as
'qBASE62ENC_TIME_OF_DAY-XXXXXX.msg' (there's an
overcomplicated test in directory_file for the
extension because in an ealier version I changed
that based on Spam score too.
So my mail is delivered based on Username, or to one of
two spam 'usernames' to pre-sort the mail for review:
# from my transports section:
local_delivery:
driver = appendfile
directory = /MAIL_DIR_PATH/${if def:h_X-HighSpam:\
{zhighspam}{${if def:h_X-Spam-Mail: \
{zspammail}{$local_part}}}}
directory_file = q${base62:$tod_epoch}-$inode.\
${if def:h_X-SuperSpam:{msg}\
{${if def:h_X-Spam-Mail:{msg}{msg}}}}
delivery_date_add
envelope_to_add
return_path_add
# group = mail
initgroups = no
mode = 0666
mode_fail_narrower = no
check_group = no
check_owner = no
# 'group' is commented out because I am running on Cygwin
and don't seem to need such complications.
#I have ACL DATA warnings to add the needed Headers:
warn message = X-Spam-Mail: yes
condition = ${if <{$message_size}{250k}{1}{0}}
spam = herbm/defer_ok
# 12.0+ point spam
warn message = X-HighSpam: Message exceeded spam score threshhold.
condition = ${if <{$message_size}{250k}{1}{0}}
spam = herbm:true/defer_ok
condition = ${if >{$spam_score_int}{120}{1}{0}}
...etc....
I hope it gives you some help and some ideas.

# FYI: I also add the "score" with the spam marker (***)
to the subject line of each mail (in the ACL DATA checks):
warn message = Subject: ***** SPAM *****__$spam_score $h_subject
condition = ${if <{$message_size}{250k}{1}{0}}
condition = ${if <{$spam_score_int}{100}{1}{0}}
spam = herbm/defer_ok
warn message = Subject: ***** SPAM *****_$spam_score $h_subject
condition = ${if <{$message_size}{250k}{1}{0}}
condition = ${if >{$spam_score_int}{99}{1}{0}}
condition = ${if <{$spam_score_int}{1000}{1}{0}}
spam = herbm/defer_ok
warn message = Subject: ***** SPAM *****$spam_score $h_subject
condition = ${if <{$message_size}{250k}{1}{0}}
condition = ${if >{$spam_score_int}{999}{1}{0}}
spam = herbm/defer_ok
