How to pass token to prebuilt panel

[mxh7777]

Hello,

I have a prebuilt panel that looks like this

<panel>
  <chart>
    <title>$titlePanel$</title>
    <search>
...

I'd like to call this prebuilt panel several times in my main dashboard but I don't know how to set the token $titlePanel$ to have different tilte on each panel

I tried this but not working

<form>
  <label>My Label</label>
<row>
    <set token="titlePanel">Title 1</set>
    <panel id="chartPanel1" ref="my_prebuilt_panel"></panel>
  </row>
  <row>
    <set token="titlePanel">Title 2</set>
    <panel id="chartPanel2" ref="my_prebuilt_panel"></panel>
  </row>
</form>

 Is there a way to do this ?

Thanks
