How to get the segment IDs of cross file repetitions via the API?

Hello, I am trying to fetch the segment IDs of cross file repetitions via the API, in a merged xliff. Trados Studio UI injects this information when you Analyze a file with an empty TM by providing these elements in the <doc-info>:

<doc-info xmlns="">sdl.com/.../1.0">
    <rep-defs>
    <rep-def id="JzFVytbB/dtRXmLFj8jObLBhpts=">
        <entry tu="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" seg="1"/>
        <entry tu="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" seg="2"/>
        <entry tu="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" seg="3"/>
        <entry tu="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" seg="4"/>
    </rep-def>

This is exactly the information that I am looking after, but I need this via the API, not by using Trados Studio UI. I have seen this page in the docs: developers.rws.com/.../Sdl.FileTypeSupport.Framework.BilingualApi.IRepetitionsTable.html and it says: 

It is left to the implementation to determine how repetitions are calculated and propagated.

Does this mean that the API does not support this functionality? Please advise. Thank you.
