в общем случае можно сделать виртуальный пин
Dynamic Virtual Pins
Virtual pins (those without an Allegro fixed tee tolerance) are free to move before, during and after automatic routing. This capability enables connection percentage, connection length, via count and adherence to length and delay constraints to be optimized while observing user-specified virtual pin position/radius and etch/via keepouts. This is especially important where you must complete multiple H-Tree solutions, as is generally the case with memory buses.
Additionally, during interactive routing, you can manipulate a routed virtual pin as easily as an unrouted pin using full push and shove capabilities. If length checking is activated, timing is automatically re-evaluated after manual virtual pin movement. However, no automatic adjustment of tuning lengths occurs (as with the autoroute process).
и сделать на него fanout если вам надо строго в определенное место развести
либо ограничением и направлением разводки
