Confiforms - Navigate JSON dynamically

[Demolag]

Hi,
In continuation to previous questions, is there a way to dynamically navigate a json based on entry parameters?

for example, I work with a webservice that doesn't let me filter the respond in the way I need, and I want to filter a specific part of the respond based on the entry's parameters - i.e. - iftttResult.asJSON.get([entry.index]).

I saw on the wiki that both on the JSON navigation guide, and both the get() and asFilteredBy() virtual functions don't work using entry references. Is there another way to do it?
