Yes. Each channel on the 7708 card can have it's own function.
For example.
Channel 1 could be Temperature with type T thermocouple.
Channel 2 could be a four wire RTD (Please note this would gang channel 22 for the four wire connection).
This is simple to set up in the Excelinx-1A software
Look at the DMM CONFIG sheet. Line 36.
Set channel 1 for function = Temp
Set RANGE to T
Set Option to INT
Now set channel 2 to Temp.
Set Range to PT100
That should do it.
