Filter Tags in Orchard CMS to only Blogs

Question

In Orchard CMS, I'm trying to find a way to filter the Tags in the Tag Cloud to return tags only from blog posts. Right now, the Tag Cloud returns tags from all content types.

I'm using the default Tag Cloud in Orchard 1.7.1.

If there is a setting in admin, great, if not, I found a query in TagCloudService.cs. Is this the one I need to edit. If so, can someone help me with the filter I need to add here to include only blog posts

tagCounts = _contentManager
                .Query<TagsPart, TagsPartRecord>(VersionOptions.Published)
                .Join<CommonPartRecord>()
                .Where(t => t.Container.Id == containerId)
                .List()
                .SelectMany(t => t.CurrentTags)
                .GroupBy(t => t)
                .Select(g => new TagCount {
                    TagName = g.Key,
                    Count = g.Count()
                })
                .ToList();

Thank you

Replace the call to Query with .Query().ForPart<TagsPart>().ForType("BlogPost").ForVersion(VersionOptions.Published).Join<TagsPartRecord>().
