Hi,

I’m sure this is possible, not too great myself with the portal customisations but worst case you can get Freshservice to do the customisation for you (at a fee). 

How are you separating your tickets? are you using workspaces?

Yes I am using workspaces. 

Great at least you have a way to easily identify the tickets. Have you looked into the no code portal designer on the service desk rebranding page in global settings?

Yes I have, and I cannot seem to find any tag or filter information on how to specify the tickets it displays.

This is the Ticket list page, which sounds like a good place to start - either to be able to add a filter for IT or HR workspaces, or to create a toggle for users to filter it. 

<section class="page-wrapper" id="sec-ticket-list">
  <section class="page-header">
    {{> ticket_filter}}
  </section>
  <section class="page-body loading">
    {{> loader}}
    {{#paginate 
      list                = 'ticket.list' 
      id                  = "ul-ticket-list" 
      class               = "list-container" 
      perPage             = 10 
      params              = ticket_params
      paginationContainer = "nav-ticket-list"
      }}
      <a href="/support/tickets/{{display_id}}">
        <h3>{{subject}} <span class="display-id">#{{human_display_id}}</span></h3>
        <p>
          <span class="created-on">{{translate "portal.created_on" created_on=(dateFormat datetime=created_at formatType="dateTimeWithoutSecsAt" showTime=true)}}</span>
          <span class="source source-{{source.id}}">{{translate "portal.tickets.source_via" source=(unescapeHTMLEntities source.name)}}</span>
          {{#if responder_id}}
            <span class="assign-to">{{translate "portal.tickets.assign_to"}} {{unescapeHTMLEntities responder_name}}</span>
          {{/if}}
        </p>
        <span class="status status-{{status.id}} {{#if active}}active{{/if}}">{{unescapeHTMLEntities status.name}}</span>
      </a>
    {{/paginate}}
    <nav id="nav-ticket-list"></nav>
    <div class="no-result-container">
      {{translate "portal.tickets.no_tickets"}}
    </div>
  </section>
