Creating links & Filtering Categories across multiple Galleries

I am trying to create a portfolio site..(Im using Avenue) I will have multiple galleries of different projects in an index page. I would like to be able to have links to filter the portfolio content. I know I can create Catergories for images within a gallery, and filter within that gallery... is there a way to filter across multiple galleries?

I.e. I'd like to have categories like Branding | Website Design | Infographic Design | Marketing Collateral and then when say Infographic Design is clicked upon, only galleries that have an image with the Category Infographic Design will show up.

Similar to what http://thefalconlab.com/ does.

See this other question, posted minutes ago: https://answers.squarespace.com/questions/279438/how-to-display-both-categories-and-tags-on-a-produ.html

Is there an answer to this? That second post is gone.

My original post said:

You can filter by tags and categories using links, but some use cases are easier to achieve than others. For example:

• You can filter by a category and a tag, showing only results that meet BOTH requirements (those that are of the category AND of the tag).
• You cannot filter by multiple categories, showing ONLY those that meet ALL the categories.
• You cannot filter by multiple tags, showing ONLY those that meet ALL the tags.

There's a plugin available that makes this much easier: Universal Filter.
