WP to Multiple Tumblr blogs based on Category

First of all apologies if this is in the wrong area here.

Looking for a plugin or widget that allows you to cross post a WP blog entry to any number of different tumblr blogs based on the category for that particular post.(And without having to change the link before posting such as in Publicize – would like it to remember the details of say 3 tumblr blogs and allow you to pick and choose whichever)

Don’t want all WP posts to be sent to one tumblr blog (as seems to be usual), but by clicking a button or ticking an option will allow you to choose which tumblr blog to post it on for each individual post on creation. Does anything exist that can accommodate this request at this time?
Thanks for reading 🙂
