More consistant System Prompt Influence

Is there a way for system prompts to more consistently influence responses rather than just the first few or several prompts? As far as I understand there’s some mechanism to re-introduce the system prompt now and then but it feels like the majority of the time if your using lengthy chats the System prompt isn’t really present and you need to manually remind it of how to handle certain things regularly, such as not being censored, treating you like an adult or even some random companies guidelines don’t apply to you as you don’t work for them. This issue varies between models so I’m uncertain how much Venice can do about it.
