Im back...

My case: I have setup so when my player reaches the first NPC, a dialogue starts with an cutscene.
Basically the NPC tells in the dialogue which first object/target he has to destroy.
I would like that after this conversation, to add the mission object as text in my questlog.
And like wise when i kill my object, i would like in the quest log that the first objective is marked of as completed somehow..
Also can i add pictures/images to the questlog? I want to show the target..
I hope it all makes sense..
Thank you
