SQL & PL/SQL

My requirement goes like this

SS_ADDR_AVA_ARR is a VARRAY

SELECT SOURCE_NAME BULK COLLECT INTO SS_ADDR_AVA_ARR FROM SOURCE_SYSTEM_CONFIG_TABLE WHERE ADDR_DATA_AVAILABLE='Y';

I would like to check the values of VARRAY in a single shot instead of LOOPING,
But PL/SQL doesn't allow SUBQUERYING as below

EXIT WHEN V_DG.SOURCE_NAME NOT IN (SELECT * FROM TABLE(SS_ADDR_AVA_ARR AS VARCHAR2));

OR

IF V_DG.SOURCE_NAME NOT IN (SELECT * FROM TABLE(SS_ADDR_AVA_ARR AS VARCHAR2)) THEN
--CODE

END IF;

How to go ahead with this
