You can configure asset types to open in the generic form for editing, instead of the default form that opens for each specific asset type. To do this, navigate to Configuration > Repository > Form type mapping.
By default, the asset types are set to not open in the generic form. Select Yes to configure an asset type to open in the generic form. The setting will apply when editing assets or when editing approval tasks for Smart Harvesting (see Author Matching Approval Task List).
