twitter for windows phone, how to delete complete direct message threads

[davegore]

hope anyone can help with this, as the thread says above, i cannot work out how to delete a whole conversation in the messages of twitter, i can delete single parts of a thread/conversation by holding down the individual one, but for the life of me i can't work out a quicker way to delete the whole thread

in the message tab there is a link at the bottom by the 3 dots to mark all as read, but nothing further than that, please help, because to delete a whole thread one by one is frustrating
