ability to post custom tweets

so im familiar with the social sharing feature built into Model centro for twitter however i would like to suggest the ability to have the option to create custom tweets in the section where you post content in the my site/videos or photosets section.

when you add a new video or photoset have a twitter field that allows you to put in custom description that way when the content gets posted in model centro and the tweet goes out there will be a better description about the content itself as opposed to using 1 generic message thats being offered in the social sharing / twitter section

this suggestion will be good because this will allow us to create specific tweets for themed days such as tittytuesday , asswednesday, friskyfriday ect.... more sharing = opportunity for more sales!!!
