[Plugin: Add Link to Facebook] Posting to multiple pages and/or groups?

Is there a reason why it is not possible to post to multiple pages? Also is there a reason why posting to a page or a group is mutually exclusive (i.e. only one or the other is an option)?

I manage various pages and groups all related to my work. Sometimes I need to post to more than one page and/or to a group AND a page at the same time. Is it possible to make this an option in this great plugin?

By the way, this plugin is the most feature rich Facebook Connect type plugin I’ve seen, and I’ve tried all of the main ones.
