What happened to delete duplicate positions or 0 speed extra positons?

[RsH]

I am now using the latest version for the first time in several months, and cannot see how i can have the program find all duplicate positions and then delete all but the first or the first and the last of those many duplicates that are recorded when I've parked the car in a shopping center parking lot for a while. Has it disappeared? Deleting manually can be a real pain when it amounts to hundreds of positions, as my ASUS R300 saves one position per second.
