How do I control Blocks on the "My Account" page?


I am stumped with this one. When my customer clicks on the My Account or Gift Certificates page,they have to scroll down past my catalog before they see the sign in fields. I have been to Design_Blocks page and the only way to disable the Catalog block is to select All Pages and disable this block. This kinda defeats the purpose. All my active blocks are showing up on these pages. How do I disable blocks on the My Account and Gift Certificates pages???
