I'm afraid direct european, canadian, and australian support narrowly missed the cut this round. It is relatively easy for an eCart owner to make those changes, but I'm sure we will address them in the next release.
The primary purpose of the address information is to use for shipping and google maps, which don't require the second line of the address, but it is a good suggestion and very easy for us to add, so I will log that request and see if we can get it updated.
Did this help? Tips are appreciated...
