Removing or editing tree entry

Does anyone know if there is any way of removing a specific entry from a tree or perhaps just editing/overwriting over it. I am trying to log information about glue mixes however since the procedure gets broken up into two sessions which are days to weeks apart I need to be able to reload the information and add to it. I was hoping to use a tree for easy comparisons between batches; however, I can’t find a way to edit an entry once it has been written to a tree. Has anyone tried something similar and have a solution?
