Let’s go for a refresh.
I desesperatly would love this feature 😊.
Today I use locus Map, in which I save all my activities in addition to SA, to be able to find again an old activity I did, passing at a certain place. At the price of quite huge data base, locus enable to display lots of tracks and click on them to select.
It is not possible in SA (path are not click able, just start points) , but with kind of map date filtering, it could become feasible to focus on very limited dots to click).
