Need to be able to exclude specific pages/posts

(using PRO version) I need to be able to exclude specific pages/posts when using an option other than “Site Wide”.

For example, I have Google Tag Manager Body code to add on my entire site except one page. When I choose “Site Wide” I can exclude that page, but my only placement options are Header/Footer. When I choose “Specific Post Types” I can place in Body Open, but the ability to exclude a specific page/post disappears.

Please add functionality to exclude specific posts/pages when using a placement option other than Site Wide.
