Hi, i need your help, in gta 5 i have installed markers but now if i quit the game, the markers will not be saved right ? Now i need your help because i don't know how to save markers, someone know how ? please answer quickly, thanks

Please i need your help, i know this is not too much related to this but tell me here please, do you have gta 5 dlc vehicles? because I don't have them, they don't even disappear, they aren't even offered there at spawn in menyoo, I tried with trainerV but it's also impossible to spawn, if you have online vehicles tell me how to have them.
