You can insert arbitrary numbers of vias before you start the toporouter
-- it may use that vias, or do not use them, that we may tell it. But
there should be NO existing traces when you start the router. I admit
that is an important restriction, which people may really not like. What
we may do is define keepout areas where the router put no traces, these
areas can be used for manually routing. One extreme case is, that we put
closely spaced vias where manually routed traces exists. We may insert
these vias automatically. But that would restrict the toporouter much.
