wxCrafter & wxPropertyGridManager & property pages

[coder99]

wxCrafter 2.7 stand-alone - Win 10
I am trying to use the wxPropertyPageManager and have been able to add it to a wxAUI based project.
As it is, I am quite new to these property pages, ...
I can add individual properties (as a test) directly to the manager, but I don't seem to be able to find a way to add a property _page_. Obviously I am missing something, but what?

My actual app will need to dynamically add/remove some properties (from a page), which means I may have to remove some or all properties from an existing page and, since I have no page, I have been unable to find a way to remove either all or some of the properties I have added as a test from within wxCrafter.
I suppose I could rebuild the page from scratch ... but,
Can I add property pages from within wxCrafter?
Should I be able to?
TIA
