[rules-users] Rule project referencing

Hello

I am looking for a comparable feature in drools that works similar to 
"rule project inheritance" in ILOG JRules. 

In JRules, one can define a rule project A that contains all the 
base-level rules. Then, a new rule project B can be defined that 
"references" rule project A. This automatically makes all the rules 
defined in rule project A available in project B. One can then add to that 
set of rules by defining new rules in project B or override specific rules 
in project A. This feature is very handy for setting up client-specific 
rules. You can start out with a vanilla set of rules specified in project 
A. If a particular client wants additional rules (or wants to override the 
default functionality), a new rule project B can be created for that 
client that references project A and has the additional rules. No need to 
copy-paste all the rules from A to B. That way, if a rule is fixed in A, 
all referencing child projects instantly benefit from the update.

Is there a similar feature in drools or a way to achieve the same 
functionality?

Thanks
