Total messages badge at the home screen of Pushover

It would be a very nice feature, if u could place a grey badge with the total amount of messages that are inside the 'All Messages' category. If i go to All Messages and leave the category i would like to know how many Messages are inside. As an example i keep track how many new users i've got per day for an app, and clean the messages also per day. But during every day it would be nice to see a total amount of all the messages.
