Hi Darek,

I can reply very shortly to this I'm afraid : no.

The filter parameter in Leaflet map plugin was only designed for tiddlers. 
And I guess that filter in TiddlyWiki was not designed for such complex 
json neither. May be Joshua's JSON mangler plugin can help? I do not know 
them enough to say.

As a workaround, you may convert your json data to tiddlers with an 
external script, import them and then use filter.

Cheers,

Sylvain
