Hi Guys,
lets said i got a board with 1-2-1 structure.
Scenario 1: when i punch the via directly from top to bottom, the distance between microvia to microvia is 0mil according to what i set(beautiful)
Scenario 2: when i stop at L2 and restart routing again i cannot get 0mil distance directly(i need manually route and place the core via).

Question is, any way to improve the second scenario?except delete the L1L2 microvia and re-route again.=(
