It does take a lot of slotdef attributes to do this, but there does not appear to be a practical limit for the number you can use. Write a tiny program in your favorite scripting language to make the list of attributes, and append it to the symbol file. A great advantage of a well documented text-based file format.

Another way is to use my pins2gsch script to map a table of pin assignments into a non-graphical pseudo-schematic. When I do this, on another page I'll draw a bus representing the wires going to the connector, and then terminate the bus at a degenerate symbol (just a box and text, no pins) representing the connector that also serves as a place to attach the necessary attributes for layout and BOM (mainly refdes and footprint).
