No. irl we insert the Sid then click on the last waypoint and from there we can put in all the waypoints we need. Note that this is only happening when the flightplan init insert isn’t used.
In real life the flight plan init insert, you click on it, enter the aircraft info, and company code and the route just immediately pops up covering up the sids and everything. So it’s very unpleasant for me to add waypoint by waypoint taking like 20 mins for a 2h flight.
