I'm designing a 4 layers PCB in Altium Designer 19.1. My PCB have a ground plane on layer 2 and a small copper pour area on layer 1. The copper pour area on layer 1 is connected to the ground plane using vias. Currently those vias have thermal relief on layer 1 and 2 but I would like to change the polygon connect style of those vias to direct connect. I have other vias, outside the small copper pour area of layer 1, that connect to the ground plane on layer 2. I would like the polygon connect style of those vias to remain unchanged. How could I do that? Would creating a new polygon connect style rule with the query TouchesRoom('Name Polygon Layer 1') work? I suppose it won't since polygons and rooms are two different things.
