Delete way points in itn routes

[Hodi42]

Hello, I’m using a Rider 550 and mostly import Routes in ITN format because I want to import specific waypoints to pass. Sometimes I need to reload the ITN route having already passed several waypoints which I then have to delete. I know how to delete them one by one but if you have a dozen to delete the process is a bit long. In the menu “actual route” of the Rider there is a function “reorganize waypoints”. Couldn’t you make a similar function with “delete waypoints”? Kind regards.
