Global Site Tags not showing custom taxonomy

Hi,

I have post indexer running, which is showing some url issues as posted here:
https://premium.wpmudev.org/forums/topic/post-indexer-adding-blog-to-permalinks-of-sub-sites#post-979779

However the Global Site Tags widget is not showing any of the custom taxonomies which are applied to custom post types on the sub sites.

Is there any way to include custom taxonomies in the global site tag widget?

Thanks
Alex
