save a position inside a recording route

hi guys, here my question:
I'm a mushroom searcher so i would like to record a track with my fenix 5 with the possibility to save on the tracks some exact locations on the route (locations where i find the mushrooms)
I know i can save position on fenix 5 but this position are not linked to the route, route and saved locations are two different things.
For a better understand i would like to be able to obtain a result like this one where there is a track and some position marked on the track all in a unique file.

Is it possible?

thanks a lot for the help
