Custom mesh placement

Everything worked on it's own expect the custom mesh placement. It's a problem of getting some reference to the selected mesh and getting an asset path. I was able to make some graph calls that lead to getting one of that path into a string variable and use a different Python execute that can take that variable:

So now it works but I will still need to work on it once I successfully publish because the logs indicate that I need a specific reference and that the one that's being taken will be deprecated in the future.

Otherwise i think I'm almost done. I've said this so many times but I can't wait to show this off.
