Ya, it's 100% possible, only to the games that you are able to mod as of now. Such as gears of war, fallout shelter, cuphead etc. You just open your saves on those games, click on the save (not the far right of the save) and save it wherever you want. If you want to replace it, click on the far right of save where it looks like a box with an arrow coming from it pointing upwards, then find a save and open it. It will then replace it.

If there are no saves at all, then Vantage is glitched. Simply log out, sign back in. If you can't sign back in, don't worry, it happens to all of us. Just wait 5-10 mins, and then you should open up your saves and such

Thanks.

I found that if you don't upload to the same save slot, the save don't show up for me, so also make note and upload the backup save slot only, if needed.
