Hello Sumit,
That is quite a hack but you can use it. Please note that the SYSTEM/ADMIN user if he sees the Space.me he would see both the scenarios with same name. If that is not the usecase and you are sure that only individual users will access it then you can sue it.
There is yet another way. All the indicator or measure generates a Calculation View in gen folder (- to know more about the nomenclature please read the developers guide-). Also there are analytical privileges created for these calculation view. These privileges are provided to OPERATOR role. You can also think of creating your own roles with respective analytical privileges and assign those roles than OPERATOR role to your users. But please be aware that regeneration might have problem due to cross dependencies etc.
regards,
Archana
