How to set a drop-down default value for a linked form when used by itself?

[rsxrox]

I currently have a form that is a destination form for a dashboard drilldown. Upon clicking a value on the pie chart on the dashboard, I'll be directed to this form with a token $version_remote$.

        <drilldown>
          <link>/app/myapp/destination_form?version_remote=$click.value$</link>
        </drilldown>

This form has an input drop-down. I've set the default value of this drop-down as the token from the source dashboard drilldown link ( $version_remote$)

  <input type="dropdown" token="version_local" searchWhenChanged="true">
      <label>Version:</label>
      <search>
        <query>index=myapp sourcetype=my_app_csv | stats count(app_id) by app_release| sort -app_release</query>
      </search>
      <fieldForLabel>app_release</fieldForLabel>
      <fieldForValue>app_release</fieldForValue>
      <choice value="*">All</choice>
      <default>$version_remote$</default>
    </input>

I'm also going to use this form by itself (not thru dashboard drilldown). When using the form by itself, I'd like the default value to be set to 'All'.

Can you please let me know how I can do this using the same form?

In the drilldown dashboard, keep the token name for the dropdown same as what is being passed from other dashboard and set the default to all. Something like this (remember to update all reference of versionlocal with versionremote)

<input type="dropdown" token="version_remote" searchWhenChanged="true">
       <label>Version:</label>
       <search>
         <query>index=myapp sourcetype=my_app_csv | stats count(app_id) by app_release| sort -app_release</query>
       </search>
       <fieldForLabel>app_release</fieldForLabel>
       <fieldForValue>app_release</fieldForValue>
       <choice value="*">All</choice>
       <default>All</default>
     </input>

Cool, this worked. Only other change that I had to do was change the versionremote in drilldown tag in the source dashboard to form.versionremote, like below.
<link>/app/myapp/destination_form?form.version_remote=$click.value$</link>
</drilldown>
