Activation of the System Preview individually for each Document Display/Document Class

The OutsideIn Viewer and the System Preview have different advantages and use cases for displaying documents in the winCube. For example in some applications we need the OutsideIn Viewer to show annotations like stamps on excel files. In some use cases the users need to see the raw excel file, especially when the excel is not shown correctly in the OutsideIn Viewer.

Currently it is only possible to completely enable or disable the system preview for a mime type for the user. We would like to be able to configure the system preview for each document view or document class individually.
