I am working with some custom profiled extrusions that have regular cutouts for mounting hardware (think a bar with slots cut every 6 inches), it would be really helpful to be able to create a weldment profile that when extruded along your frame lines would have these cuts made already.  Making the profile shape is not an issue and making the cuts is not an issue, I just wish that I didn't have to make all the cuts everytime I use that shape.  Is something like this possible?

Thanks
