Condition Statement Builder?

Got it.

Depends what you specifically meant by "is it safe", but there are no technical reasons you shouldn't consider keeping some rules in DB and filter through uploads based on that.

Some setting pages could get complicated and take long time to implement, but my golden rule is - would it take too long to deploy manual logic changes and/or would I be annoyed if I had to always change the logic on code side? If the answer is YES to either, I build settings page that other employees can use to adjust application behavior
