Bug 24480 - There is no good way to set checkbox based items using global variable.

[arafe102]

This is not really a bug but if someone can do it it would be great.
"For any of the text input fields, we can use ${<variable_name>} expression to use the global
variable defined for each test plan. However, for anything else such as checkbox parameters, this
is impossible unless you open .jmx file in a text editor and batch edit the entries.

This feature would be very useful. For example, I might want to turn on/off Keep-Alive feature."
"Definitely a pain, but not a bug."
user believe this should be fixed anyways.
