WordTwit and Tumblr Crossposter

I’m using WordTwit with Tumblr Crossposter. With individually, work great. The problem I’m having us that the tweets are being seen by Tumblr as their own posts, causing both the blog post AND the tweet to be sent to Tumblr.

I’ve found this about the Tumblr plugin: <<My admittedly limited understanding of how WordTwit works is that whenever a new tweet is published, it also invokes the standard WordPress post publication actions. See line 253 of its main program file, specifically between lines 282 and 292.>>

Is there a way to have the tweets have their own category to not be crossposted to Tumblr or some other solution?
