Feature Request- Seperate Categories from the rest of the Taxonomies

[cjjr82]

Hello,
First, I want to say thank you for building this plugin. It works exactly as expected without any major issues. The one thing that I have noticed, that isn't a bug but has become a small annoyance is having all the taxonomies in one list. I only have 10-12 categories on my site, but over 10000+ tags. So when loading the list of taxonomies, it takes some time for the list to load for each conditional logic I apply. So, if possible, it would be awesome if the 1st select could include it's own 'Post Category' option, then only list the sites categories in the 3rd select.
Again, not a deal breaker on using the plugin, so thanks for the work you've done on it!
