Change Revit Link Display Settings and Design Options using API

Hi,

We are developing a plugin that automatically selects the Design options for all the linked models based on an external file (that external file is not even Revit, it could just be a JSON file that lists the design options for linked files).

Basically, we'd like to automate the following screens:

1. Clicking  Edit Visibility/Graphics Override
2. Navigate to "Revit Links" and for each Link, do the following steps:

     a.  Click "By Host View"

     b.  Select "Custom" (Screenshot 1)

     c.  Navigate to "Design Options"

     d.  For each Design Option Set, select the Design Option from the external file (JSON). (Screenshot 2)

We have seen APIs for Categories and Filters, but we weren't able to find an API for Revit Links. We'd be grateful if someone could point us in the right direction.
