How can I use a vpwlf source with design variable for filename in AMS simulator (with UNL)?

I found the same topic for the spectre simulator:
support.cadence.com/.../cos;solutionNumber=11366978
But actions discribed there not suitable for "AMS Unified Netlister".
UNL take the cdf simulation information from ams section.
I performed the actions from topic in cdf section for ams simulator, but it did not help.
