DS DataStore on MS SQL Server - Dirty reads

Dear colleagues,

Is there any way to set ability for dirty reads from MS SQL Server  only for needed DS DataStores ?

now as i understand from wiki - we can set this only for whole JobServer .

Turn on dirty reads: If you are absolutely sure you read the data first and then you update it, we do not care what data we read. We can ask SQL Server to perform the select without applying a read lock. So go to the DataServices bin folder of the jobserver, open the file DSConfig.txt and in the AL_Engine section add the line SQLServerReadUncommitted  = 1.
