Not able to create a view for Merged Accounts in CRM 2011

I want to create a view where Merged = Yes or MasterId contains data in Account entity, I am not getting Merge fields(Merged,MasterId) in View Filter Criteria. Is there any way I can create a view with these fields?

Requirement is Business users should be able to see what accounts are merged. Is there any other way to accomplish this in CRM 2011 UI customizations?

Thanks.
