Hi, Karguy. For auto split in "Live split", I use "AutoSplit Helper". URL : https://frailleaves.com/myownsoftware/autosplit-helper/ There is an article explaining how to set it up to measure every 10 meters, but it is in Japanese, so please use a translation tool. URL : https://kuro1san.hateblo.jp/entry/2021/01/31/105447 If you can't read it due to garbled text, I will create a separate article with a machine translation into English.

Of course, if you learn how to use "ASH", you can create a simple split with only a start and goal point as well as a setting to measure every 10 meters.
