What I do is split MCUs up into functional blocks - one block for all
the power/gnd pins, one for ISP, one for external memory bus, etc.
Then you can fiddle with block variants on a per-project basis.

As for design-specific pin functions, what I do is leave the symbol's
pin named according to what the mcu's documentation uses, so that I
can remember what pin it "is" according to the mcu.  Then I label the
net coming out of that pin right at the pin, with its design-specific
purpose.

So, a pin that's GPIO port 9 bit 4, that's TxD3, that I happen to be
using for the console, might be named P94/TxD3 with the net named
CONSOLE_TX.
