Google Trends Parse By Category

I want to parser Google trends keywords by category.

I have a list of all the Google trends category ids and I am using query builder to create a list of queries using the category ids so I can parser through all the categories.

But I am having two issues:

1) I can't seem to figure out how to dynamically insert the category ids into the "search category id" field.

2) To just get top keywords from each category you need to leave the keyword query empty when using the web interface. I'm pretty sure this is not possible in the parser. Would it be possible to add this option so we can grab keywords by category? If not for everyone how about a paid customization?

Here is what I am trying to do:
