Create a new column adding _measurement as suffix

Hello, I’m trying to create a new column in my series, using _measurement value as prefix.
Is there any way to make it?

I need that because I’m aggregating some series but I would like to keep the real timestamp for each serie as a new column in my pivot result. So I would have something similar to it.

_time | measurement_1 | _time_measurement_1 | measurement_2 | _time_measurement_2

12311 | 50                       | 12322                            | 60                       | 12320

Example of query

from(bucket: "test")
    |> range(start: v.timeRangeStart, stop: v.timeRangeStop )
    |> filter(fn: (r) => r["_field"] == "value")
    |> aggregateWindow(every: 10s, fn: last, createEmpty: false)
    |> limit(n: 1000)
    |> pivot(rowKey:["_time"], columnKey: ["_measurement"], valueColumn: "_value")
    |> drop(columns: ["_start", "_stop", "_field"])

thank you
