Movement type and Value string

Question

Hi,
I have copied movement type 101 to Z02. Is it possible to change the value String from WE01 to something else. My purpose is to post to a different account instead of GRIR while MIGO for free goods. So please don't suggest me to change in OBYC as the change is going to effect every MIGO which we don;t want to happen. Any ideas?
Thanks

The value strings contain keys for the posting transactions that can       
lead to G/L account updates in the case of an FI-relevant posting. These   
value strings are predefined by SAP. You cannot change value strings or    
the transactions they comprise in Customizing. For each of these posting   
transactions, you can set up automatic postings in dependence on the       
other influencing factors.                                                                               
The value string controls the process of G/L account determination for     
transactions/events of the movement type (see unit Valuation and           
Account Assignment), whereas the quantity string controls the updating     
of the material master fields.                                                                               
In SAP R/3, the value string WA01 is assigned to various goods issues      
and other goods receipts. Further differentiation in the automatic         
account determination process for these different movements is             
accomplished via the account grouping code.
