Each post shows which of your saved places it relates to, by displaying the places' nicknames at the top left.
For example, if you have saved three places (your home, your work and your rental property for instance) you will see that for a Rates Reminder (a district wide message) all three nicknames appear at the top as this post is relevant to all three places.
As another example; if you have saved both a rental property and your home property in Antenno and you receive a refuse and recycling collection update, you can tell which property it relates to by checking the nickname.
