draw your polygon with the poly tool, name it gnd (or what ever name
you are using for ground) then route. You will see traces run though
the poly. I've never liked how the resulting traces looked in the gnd
poly so I've not made a board that way.
you can increase the size of a via by changing the drill size but
that leaves the narrow pad. Its not immediately obvious how to get a
big "pad" and small drill for via.
