Hello and welcome back to the community. I hope you’re doing well. 
Thank you for taking the time to share such a thoughtful suggestion. Feedback like this is genuinely helpful, as it gives our trainer developers a clearer picture of the kinds of options players find most enjoyable and accessible.
If you’d like to propose a new trainer option, the best place to do so is in the official forum thread for that specific trainer. For example, the discussion thread for Dark Souls 3 can be found here: Dark Souls 3 Cheats and Trainer for Steam.
Please keep in mind that, while our trainer developers are always open to ideas, they’re limited by what the game itself (and the way it is coded) makes possible for them to create cheats for. Certain features simply can’t be implemented if there are no suitable memory addresses to work with, or if the modification would cause instability or lock player progression. As a result, not every suggestion, even those that seem straightforward, can always be added.
Nonetheless, your input is very much appreciated, and sharing it in the relevant trainer thread ensures it reaches the people best placed to explore what might be feasible.
Have a fantastic day & weekend!
