Is there a way to access Database Explorer outside of Toolbox, or to direct it to load/explore a database other than the one currently loaded?

Specifically, we are running library 44.1, but I also have library 50.5 installed as a separate database configuration to poke around and see some of the updates. Sometimes I want to take some of those items from 50.5 and modify them to use with 44.1, but to have to shut down Toolbox every time I want to switch which database Database Explorer accesses is very annoying and time consuming. So I was wondering if there was a way to keep Toolbox open in my 44.1 library/database while accessing Database Explorer from outside Toolbox and directing it to the database that has the 50.5 library.

I also don't want to try to add 50.5 to the database that has 44.1 because that could potentially create unforeseen and undesirable consequences.
