Option to disable doubling bpm when analyzing tracks

I noticed that when you select a range ie 70 - 180bpm and you analyze a bunch of tracks, and track that is outside this range will be doubled. ie a 60bpm track will be doubled to 120bpm. You will be left with a mix of slow and fast songs on the same bpm. This should be an option to either maintain the original bpm or go ahead and double it or there should be an auto range feature that let's BPM work with any range not what is selected.
