BW objects in HANA studio

Gurus,

I didn't have the pleasure of working on the BW 7.3 running on HANA DB yet, so I have this question..

If BW 7.3 is running on a HANA DB, do we have any visibility of the underlying tables of BW objects like fact tables of cubes, new/active/changelog tables of DSOs in HANA Studio Content?

I know (read in one of the documents) that the tables/views in HANA Studio Content/catalog will be available for data modeling in BW to create Composite info providers. But is the reverse also true that the BW tables are available in HANA Studio?

Thanks.
