ApiServer: Configure service categories and products to display

I need a way to configure the displaying of service categories and products based on a customized query.
In the old WebDesigner you had these great configurable options for this:

VI_ITShop_Filter_AccProductGroup (Products to display for a given recipient)
VI_ITShop_Filter_AccProductGroupMultiUser (Products to display for a given list of recipients)
VI_ITShop_Filter_AccProduct (Displayed service categories)
VI_ITShop_Filter_AccProductMultiUser (Displayed service categories for a group of users)

In the new ApiServer I cannot find these configuration options externally (via the admin portal)
The queries for displaying service items and categories seem to be hard coded in the standard API plugins.

Why are these configuration options missing on the API server?
Are they planned for a future release, if so 9.3?
What would be a work-around strategy to accomplish this given the current 9.2 version?

Niels
