Split Symbol Across Multiple Pages

Question

Hello.

I have a device with several hundred pins. For the sake of organizing my schematic, I'd like to split the library symbol across two pages---I can't easily fit it on to a single page at the moment. Is this possible in EagleCAD?

Any hints or ideas on how to do this (or just make the symbol more manageable) are most appreciated.

On complex IC's, such as microcontrollers, I split the symbols into

logical blocks. GPIO A, GPIO B, Power block, JTAG block, USB, EBI, etc.

for this very purpose. The only symbol in the device that is marked

MUST is the power block. Everything else is marked as CAN. IN then use

INVOKE to place the CAN blocks on separate sheets.

DPDT relays are treated the same way. ADD places the coil, and INVOKE

places each pole.
