Multi-building placement has been implemented.
Certain buildings such as dwellings and roads allowed you to automatically place multiple of them easily without having to open the build menu again.
Single placement buildings such as farms, temples and industry buildings can now be placed multiple times by holding down left SHIFT as you place the first building as seen in the image below.

If you don't want to build the subsequent building that's fine, press escape or right click and the placeholder will vanish.
Hopefully this quick update makes it easier to build multiple buildings back to back.
