Media gallery to place favicons for sub site only shows network media files...

Thank you guys for incorporating the idea of being able to assign unique favicons to sub sites while this plugin is network enabled, it was a feedback request I made a while back.

However, this may be a small glitch or just something to suck up but... Now that I have the plugin network enabled, my first step was to assign favicons to all the sub sites. When I clicked browse, I could only choose from network media files rather than media files for the respective sub site. Is that something that was overlooked and can be fixed or is it permanent? For example, I would like to keep the favicon icon of subsite 1.mysite.com inside that sites media files so that it does not get mixed with the networks media files at mysite.com. I also tried using Insert with URL in the media gallery but it didn't work. Please let me know if this can be fixed with a plugin update soon or if I have to load all the subsite favicons into the network site before I can assign them using this plugin.
