How to set transitions to project level groups in TFS 2017

We have a TFS configuration where we defined Transitions. These transitions are at global level but now we want to move those to Project level. Ex, our TFS structure is ProjectCollection\Project1. Currently our transitions are defined in process template as -

  <TRANSITION from="New" to="Approved" for="[global]\Analysts">
      <REASONS>
        <DEFAULTREASON value="Ready to implement" />
      </REASONS>
       </TRANSITION>

Now so that we have removed this "Analyst" group from "ProjectCollection" and created at "Project1" level so our transition would be

 <TRANSITION from="New" to="Approved" for="[Project1]\Analysts">
      <REASONS>
        <DEFAULTREASON value="Ready to implement" />
      </REASONS>
       </TRANSITION>

But it is not supporting and giving error while importing the template. Error is - "Error importing work item type definition: TF26171: User/group '[Project1]\Analysts' is not found. TF26204: The account you entered is not recognized. Contact your Team Foundation Server administrator to add your account."
