Anurag, the short answer is no. But could you elaborate on your use case please? Is this a GroupSpace-level or Top-level issue?

Hi Ivan, it is a top-level blog issue. We have a few community blog channels based on substantive research fields. We need to add a blog at this level, which is essentially based on a sub-category of one of the existing channels, and so logically should be a sub-channel to it. We basically need some way of filtering by that sub-category, so that we can show just the sub-category articles seperately,through a blog widget on a project page.

I see... The only thing I could recommend at this point is to use a GroupSpace for each research field, within which you would be able to create a blog channel for each of the projects. I do not see how this can be accomplished without GroupSpaces, unless you're willing to prefix each project channel with a research field name:

• Field A - Project A
• Field A - Project B
• Field A - Project C
• Field B - Project A
• Field B - Project B

I think I have a similar requirement, where I want to be able to filter different blog categories, within a group-space. I want to add a page for a sub area of focus within the team group-space and only display the blog news for that area of focus on the new page, within the group-space.

I thought I would use a blog channel but when I add a blog channel to a group-space blog I only see one blog channel per group-space, and I don't see anywhere to add a channel in the context of the group-space.

I see more than one blog channel, and the ability to add channels, for the top level community blog. Am I missing something? 
Is there a way to add blog channels to a group space?

If I could add a blog channel within a group space it would allow me to filter blog articles by area of focus on different pages.

For now we are using a prefix in the blog article title to distinguish news by area of focus, but they all show up in the blog widget and I don't see any way to filter them.
