Can we a new subtab on Project Task from a savedsearch?

Hi,

I am trying to add a subtab on project task from savedsearch results but I could find a way of doing it from the sublists page?:mad:

As I can see, only the following records are available for adding subtabs.
-Transaction — subtabs for cash refund, cash sale, credit memo, estimate, invoice, opportunity, purchase order, return authorization and sales order transaction records.
-Entity — subtabs for customer, job, vendor, employee, other name, contact, partner and group records.
-Item — subtabs for inventory, non-inventory, group, other charge, assembly/bill of materials, kit/package and service item records
-CRM — subtabs for task, phone call, event, case, campaign and solution records
