Random value generator for same variable in json file

Hello,

Is there a way to generate random values inside the session for the same parameter.

Ex json file-

{
“age”: “${age}”,
},
{
“age”: “${age}”,
}

val ageFeeder = Iterator.continually(Map (“age” → (0 + ThreadLocalRandom.current().nextInt(100 - 0) + 1).toString () ) )

val scn = scenario(“test”)
.exec(feed(ageFeeder))
.exec(session => {
//// code to read the file using ElFileBody which replaces ${age} with randomly generated age
})

I want to generate random values for the number of times we are calling ${age} in the file.
