Yes, and you can see all four before you choose. The report runs the same disposals through first in first out, last in first out, highest cost first and average cost, and shows the gain and the estimated tax each one produces.
The gap between them is usually larger than people expect on a position built up over several years.
Which method you may use is set by your country, not by the software, so the comparison is there to inform the choice rather than to make it.
