Get the latest message from every conversation with XEP-0313?

I am using an XMPP server that implements XEP-0313 to get a conversation history. I would like to receive only the last message of each conversation, so that I can create a list of your last conversations by looking at the last message.

I managed to get all the messages from all the conversations and based on this I could create a list, but this is a big waste of data, not an option. I'm not sure if this is the right extension for this, so if there is another extension that I should look at, please direct me in the right direction.
