can Contract Lines DFF context be defined at Org level ?

All,

Would like to know if  we can have org_id context for "Contract Lines" Descriptive Flex Field ?

We can use LSE_ID as context for example, to enable DFF at contract subline level (show DFF if LSE_ID=9, by which DFF can be enabled for "Product" at subline level).. But this makes DFF applicable for all orgs (assuming we are using to implement contracts for more than one org or site).

Currently this DFF uses "OKC_K_LINES_B" table in which there is no org_id. 

So, my questions are-

1. can we define org_id as context for this DFF? Is that possible ? if so, please let me know how to do that. Also,  we need to have DFF for ORG_ID+LSE_ID combination too, is that possible ? if so, how to do that ?
