If there is no way to do it with ASCii Importer then how about importing data using AFL? You would just need a "for" loop like the one below to extract the last line in the data array, but I don't have a clue about the rest of the code needed for importing data (if it's possible at all), I couldn't find any examples in AFL Library:

for( i = BarCount-1; i < BarCount; i++ )

I export data using AFL all the time, here is example (the code is based on Graham Kavanagh's code from AFL Library):
