Results always default to category page

To the developer: If I need to customize the plugin to achieve this functionality, I can pay! Are you available?

Basically I am sorting with standard shortcode:

[searchandfilter taxonomies=”category,post_tag”]

If I am on a tag page and I select a category and a tag using your plugin, the plugin will jump to the category page instead and default to:

http://www.mysite.com/mycategory/?tag=mytag

How does it choose the priority? Can I have it stay on the tag page?

Ex. Is there any way to make it so that if I am already on a tag page and I select a category, it will stay on the tag page and display the results as:

http://www.mysite.com/mytag/?category=mycategory

Thank you!
