Some clarification on this topic is in order, I think.

It is the case that this is not supported by sysinst.
If you think this is a sufficiently common case, you could
submit a change-request PR asking for that functionality.

I think you would be best off installing on drive 1 with no swap
partition and then adding in the swap later. Adding the /home partition
in should be trivial as well.

While this is one opinion, I don't think it's the opinion of most people.
There's no real documentation on this, and it's really not recommended.
It may be useful in some situations, but I don't think "much easier"
is at all justified.

NetBSD doesn't have "howto"s. It is best that documentation be in-tree.
It is sometimes acceptable to have out-of-tree documenation.
