RF Toolbox AMP file

I came across this documentation page:

AMP File Data Sections - MATLAB & Simulink

But there is no further documentation on what toolbox objects support this file format. I tried to use it with an amplifier object since that seemed logical, but get an unsupported error. Can you clarify if there is any support for this AMP file format, or if there will be in the future?

>> amp=amplifier(FileName='default.amp');
Error using amplifier/set.FileName (line 182)
Unable to open file default.amp.

Error in amplifier/setParsedOptions (line 109)
                obj.FileName = options.FileName;
                ^^^^^^^^^^^^

Caused by:

    File type .amp is currently not supported by the sparameters object.
