OK I had a look at this.
The symbol pin table has UNIT field, so that should enable a unit aware import.
You might need to massage your import table to get unit allocation.
I was able to copy and paste in and out of excel just fine, modify unit allocations etc. Looks OK…
The PIN DELAY or PIN PACKAGE LENGTH field is missing from the table
I am getting that fixed . FPGA people need it here, not in 'package ’ LOL.
Also, for ease of import/export the location of the pins should not have the units mixed in with the numbers.
