Welcome to the community. 
Thank you for being Pro, which helps with the cost of trainer development and software maintenance. We appreciate it. 
We already have a trainer for this game on Steam.
See here: Alien Isolation Cheats and Trainer for Steam.
If you have gotten the game from Windows Store (for some reason), then yes, you’ll need to vote for a trainer to be made via the WeMod desktop app. Don’t forget that you have a referral link that you can use to invite people from other communities to vote while being rewarded.
See here: How do I find my referral link? - WeMod Support
A trainer for this game is very helpful indeed. Even on easier difficulties this game can be pretty hard, I thought.
