help on a post process search linked to a time input token

[jip31]

hello

In my dashboard I use 2 different token time 

Both of these token time are linked to the same post process search

Instead of creating the same process search 2 times, I would like to use only post process search linked to the 2 different token time

Is it possible please?

 <input type="time" token="timesource" searchWhenChanged="true">
      <label>Période source</label>
      <default>
        <earliest>1638313200</earliest>
        <latest>1640991600</latest>
      </default>
    </input>
    <input type="time" token="timetarget" searchWhenChanged="true">
      <label>Période cible</label>
      <default>
        <earliest>@mon</earliest>
        <latest>now</latest>
      </default>
    </input>

 <search id="hang">
    <query>index=toto sourcetype=tutu
</query>
    <earliest>$timesource.earliest$</earliest>
    <latest>$timesource.latest$</latest>
  </search>
  <search id="hang2">
    <query>index=toto sourcetype=tutu
</query>
    <earliest>$timetarget.earliest$</earliest>
    <latest>$timetarget.latest$</latest>
  </search>
