Filtering keywords for all feeds at once

I'm currently using another similar plugin to autoblog for my website http://energystorage.today. It pulls rss from 60+ sources and filters posts against a pre-determined list of keywords (the plugin I'm using is RSS Multi Importer). The list is only given 1 time.

I would like to make the transition to autoblog, but it seems that all the filter is performed on per-feed basis. This means if I would like to add a keyword, I would manually have to add it to 60+ sources, which is not feasible. Is there a way to go around this?

Thanks
