Hi @utekcnc,
In the tool library, you can right-click either "Local" or "Cloud" and then select "New Tool Library" - this creates a new library to house your tools.
Then, you can copy/paste your tools from the document into your newly created library, or you can drag and drop - whichever is easiest for you. What this will do is make a copy of those tools you want to move to the new library so that they can be referenced in other locations.
Every time you select a tool from one of your "Personal" libraries (Local or Cloud), it saves a copy to the document as well so that things don't get complicated when modifying a tool in the future.
Let me know if you have more questions!
