setting sql for a column

Hi, is there a way to set sql query for a column?

the query should take value from column in the table.

in my case, it has come down for a need to have a nested select query inside my query:

select app.application_id,
(SELECT LISTAGG(typ.verification_name, ', ') WITHIN GROUP (ORDER BY typ.verification_id) FROM
typ,chk where
chk.application_id = app.application_id
GROUP BY app.application_id ) AS verification_type,
from tablea,tableb where....
<note that application_id is coming from the bigger query , aka another column from another table.>

i've tried

CAST ( EVALUATE_AGGR('LISTAGG(%1,%2) WITHIN GROUP (ORDER BY %3 DESC)', "typ"."verification_name", ', ', "chk "."application_id ") AS CHARACTER ( 50 ))

but my query need more than few EVALUATE_AGGR resulting in huge query in the log plus it's hard to put more details from other tables when you do this since everything buble down to the group by in the end of the query.

pls help if there's something even close to this
