Ensure that pdf creation tool python is active in every instance

Is there a way to force the PDF python tool to be active in a specific thread. I’m constantly working on projects and documents that I need this tool active. I’ve been in numerous threads, in the middle of a project and the tool just goes away and I’m told that it’s no longer available in this thread and best practice is to summarize and create a new thread and “hope” that it’s active there.
