Question about waypoints and adding them via F10 map

[skypickle]

I've been flying the Viggen in the universal training mission

https://www.digitalcombatsimulator.com/en/files/3321332/

Spawning in the jet reveals there are already three waypoints. One at takeoff (Batumi, one over water and the third at the target area (old runways south of kobuleti)

I get in the jet, start up, load DTC,and check Ref LOLA and press LS. The correct airfield ID is displayed (9011). Pressing B1 and B2 shows the correct waypoint coords.

 

Then I go to the F10 map and add a little circle with the label B3 over some ships. In the cockpit I bring up the kneeboard, go to the Groundcrew settings page and change the to 'Cartridge from marks on F10 map. I then eject and then reload the DTC and repeat the instruction (9099) to the computer. But now only B3 is in the computer. I want to include the preplanned waypoints from the mission but I cannot see them on the F10 map. How do I add these preplanned waypoints to this new flight plan?

 

Do I have to get their coords BEFORE I add the little circle to the F10 map and then add them manually after I reload the DTC with the f10 map changes?

Is there a faster way?

IMHO there is no way of mixing pre-planned and F-10 map coordinates.

So, the easiest way would be to just additionally enter the coordinates of B3 (which you remember from reading them on the top left of the F-10 map), using REF LOLA > IN, ddmmss ddmmss and hit B3 button. Bamm, that's it.

It used to be that whatever you put in the cartridge would only overwrite the currently loaded data... but at some point a little while back it was changed so that loading a data cartridge will clear out any previously loaded data.

thank you both for confirming my fears.
