Include a "Content Block" or "Widget" at the sidebar via CMS page

[shahroq]

I want to include a "Content Block" or "Widget" at the sidebar via CMS pages. I already know i can do it via "Layout Update XML", but i want to know if it's possible to add it via Content section:

{{block type="catalog/product_list" name="product_list" template="catalog/product/custom_list.phtml"}}

I wonder if it's possible to add an attribute like "reference=right" to this code to tell Magento put this block at the sidebar? The reason i want to this is there is a blog add-on installed on customer store and he want to add "Content Block" or "Widget" to blog post, and the blog extension does not support "Layout Update XML".

I am sure that is not possible with this solution. All that goes into CMS page content, gets displayed within "content" block. Though, I did not really understand the "add to blog post" part.. I would suggest looking into what Magento's CMS Widgets can do - create own widget and set it to be shown in right column on appropriate pages.
