I have not used myself, but this jmeter-pluing may help you. Here is snippet from documentation

Parameterized Controller since 0.1.0

When your JMeter test plan tree becomes like a sequoia or a banyan, 
you start feeling yourself like a monkey in a jungle, jumping from 
branch to branch, trying to support this important test consistent. 
You really need some way to have parameterized subroutines, to reuse 
parts of test plan like regular programming language functions and 
procedures.

JMeter have out-of-box Module controller, but it has no parameters 
to pass to, so if you need to call repeating sequence of the same 
action with different parameters, your reflection in a mirror starts 
morphing into monkey. Parameterized Controller helps you stay human 
and sane.
