I've given up using schematics for this sort of thing.
I just lay out the board, export the net list to a table
(or spreadsheet, if you like), and then derive the mapping
between FPGA signal names and pins from that list.
The schematic is reserved for things other than connecting
100 dots on one chip to 100 dots on other chips.
