Export variables included in field_bundle_settings

Hi:

I'm trying yo make a feature which include a blog content type and some custom display modes. I'm able to export all components but which views modes are active for a content type... If I enable a views mode to have custom display settings I can see all DS settings imported via the feature. But I have to enable this view mode manually.
I've managed to found that this information is stored in field_bundle_settings system variable but I don't want to export this variable with strongarm since it contains information about all entities (not anly the blog one).

This are the lines related to DS in my features info file:

features[ds_field_settings][] = "node|blog|default"
features[ds_layout_settings][] = "node|blog|blog_list_landing"
features[ds_layout_settings][] = "node|blog|default"
features[ds_view_modes][] = "blog_list_landing"

And this is where the custom views modes are stored:

field_bundle_settings: Array
(                 
...
    [node] => Array
        (
            [blog] => Array
                (
                    [view_modes] => Array
                        (
                            [teaser] => Array
                                (
                                    [custom_settings] => 1
                                )

                            [full] => Array
                                (
                                    [custom_settings] => 
                                )

                            [rss] => Array
                                (
                                    [custom_settings] => 
                                )

                            [media_gallery_block] => Array
                                (
                                    [custom_settings] => 
                                )

                            [test_view_mode] => Array
                                (
                                    [custom_settings] => 1
                                )

                            [blog_list_landing] => Array
                                (
                                    [custom_settings] => 1
                                )

                        )
...

Perhaps this support request is best suited at the features modul, but I want to know if someone has the same issue.

Many thanks.-
