Help to texture a building

Hello working on an arch project. Need to texture up a large building. It has 1000s of windows and I’d need to select them to give them a matt ID do I can have a different material than the walls. Is there any way to quickly select them rather than individually clicking every window. Clicking every window will take more time than I have
Cheers

If all windows share similar topology to each other, you can go to polygon sub-object moe, select one window, then go to graphite ribbon>modelling>modify selection and press on select similar. If defaul setting won’t give you selesction that you want, open its settings and try different options. Quite often this tool is a real time saviour.
