Yes, you can assign a route style to each net. This is
normally done in the netlist file. The format is:

netname [stylename] elname-pinnum elname2-pinnum ...

where [] means an optional entry.
You can manually edit your netlist file to add styles
to each net. The autorouter honors each net's style
including thickness, via characteristics and keepaway.

I introduced the bug that caused the fail to connect
some time back, but it fixed it in December. The
latest snapshot release should never go almost all the
way but fail to connect. It should leave a lot fewer
nubbins (perhaps none) as well.  DJ's optimizer might
be able to automatically remove the nubbins.
