.exec(_.set("valuesperf", List.empty[String])
.foreach("#{ArrayValues}", "VValues") {
  exec(http("perftest values")
    .post("perftest")
    .body(StringBody(session =>
      s"""{
         |"id": "",
         |"perfTypeId": "00334-0000-0000-0345",
         |"legs":[{
         |      "valueTypeId": "111-220-3300-0444",
         |      "values": "${session("VValues").as[String]}"
         |    }]
         |     }""".stripMargin)).asJson
    .check(jsonPath("$.id").saveAs("perfvalue_singlevalue"))
    .check(status.is(201)))
  .exec(_.set("valuesperf", session("perfvalue_singlevalue").as[String] :: session("valuesperf").as[List[String]])
}).exec(session => {
  println(session("valuesperf").as[List[String]].mkString(", ")) // only to show the resulting value
  session
})
.exec(http("Bulk_perftest")
  .delete("/perf/bulk")
  .body(StringBody(session => s"""["${session("valuesperf").as[List[String]].mkString("\", \"")}"]"""))
  .check(status.is(204)))

Notes:

  • session is immutable, you have to return the updated value
  • preprend the list with the current value
  • use the accumulated list for the final request

Cheers!
