Not sure perhaps you could use act scripting and generate all heat generation on all the bodies in the tree and if the excel values are in order (same as in tree) then assign a value that was read in from an excel file . This is outside what we can help with, so you would need to try that - there are lots of tutorials online on the internet about act scripting that might be of help. All the best
