How to include a folder of modelfiles in Assembler/Maestro ?

We got an IP package library that comes with an OA-lib.

But the OA-lib only contains symbol and spectre view (no schematic-view).

With "spectre" view, the models for each cell must be provided by a simulation-model.

The simulation models for each cell is provided in a subfolder (e.g. ./modeltt  ./modelff  ./modelff).

Each corner subfolder consists of >50 modelfiles - one per cell.

In order to simulate the cells, we need to include the model-files in Maestro - but there is no "toplevel.scs" or "model.scs" file available which would allow to include all files at once.

Instead the customer (me) has to either:

Create an own "toplevel.scs" file with corner sections and including the path to each file in this "toplevel.scs"

or

Directly include each file in the "Model Library Setup" or "Corners Setup" GUI list - which is of course cumbersome and impractical.

Question: 

1. Is there a way in Maestro to include folders (not files) with modelfiles directly  (without creating a "toplevel.scs" file )?

2. If so, how can this be configured using ".cdsinit" ?
