GTA Trainer Question

Disclaimer: I am sorry if this is in the wrong forum, but I read through all the forums sections and this appears to be the best fit.

Hello! I have LSPDFR, some scripts/mods/vehicle textures/fallouts, and some kind of trainer too (idk what it's proper name is as I'm relatively new to modding in general, but it isn't the one that comes with scripthook. It is the other one that I think many people have). Anyways, when I first got LSPDFR (about a month ago), it was also the day I first downloaded GTA (I was console player and now I'm PC). It was a fresh copy, and I only played the prologue and the first mission. My map isn't revealed that well, just all of the LS area. In the Trainer I have, I can reveal the entire map at the click of a button! However, am I able to do that and then save? Thanks for reading!
