In my case, I am given a DXF file with the board outline, slots, holes,
etc. I then import it to PCB (import it to qCAD, print it as ps; convert
it to encapsulated ps with 'ps2epsi'; convert it to pcb using 'pstoedit'
with the '-usbbfrominput' and '-f pcb' options), so I have the slots in
PCB. I've dealt with Sunstone Circuits, who told me they can cut the
slots if I choose their full-feature service, but not the quick
turnaround service. So, I guess you could draw your slots in qCAD or
Inkscape and import them to PCB.
In fact, it seems to me you can let other programs, such as qCAD and
Inkscape, do whatever PCB cannot do very well—with the exception of
buried/blind vias and, perhaps, rotations by angles which are not
multiples of 90 degrees.
