Netbackup 8.2 NDMP policy with Wildcards

Hello

Have a master/client redhat linux server running Netbackup 8.2.

I Want to try and break up a current NDMP netbackup policy so that it kicks off groups of subdirectories one at a time using wildcards and with only one job at a time (limit jobs per policy = 1) .  

With in our current NDMP policy we have the following "Backup Selections"

------------------------------------

SET HIST=Y

/client1/

----------------------------

This volume is just over 50TB in size and Under the volume /client1/ we have like 12 subdirectories... All starting with alpha characters..

How can I use wildcards to break this volume up? or do I need to explicitly supply the full path. 

I have tried this for example 

/client/C*  as there are 3 subdir that start with "C" but I get the following error 

Error ndmpagent (pid=24809) readAllFSFromPath: No volumes found matching "/client/C*"

Also have tried :

/client/[A-C]* which also didnt work. Thinking I could grab any subdir starting with an A, B or C..

I guess if I have to list all the current subdir full paths out one by one its easy enough but thought wildcards could be used to some extent?..  If I did have to list each current subdir I guess I could create another policy to exclude the current subdirs so that it will catch new dirs that have been created.   There isnt a lot of new subdirs being created but just in case it happens at least I would be covered.

thanks
