Oh if its like a value you want to change that is for everything, I use this:
There may be free versions but basically you can access a specific datastore in studio using its key and then change a value inside the data store.
I do not own or are affiliated but I think in your case it will be quick and easy to do that then script in detection and what not.
If you want a free option I would suggest using math to compare its value and seeing if its too high or low using (> or <) and using :setasync to change its value.
