I believe not. I also want this and I did suggest it in a thread earlier. But it's really important and the more who signs the easier it is for the dev team to see what we prioritize. I qan't make fraqtals that take days to create without ever saving until it's done when windows restarts whenever it feels like it.
The Load/Unload functions have problems, yes. Good news: Olive said they found and reproduced the bug that I reported. I'm not sure if your problem is the same bug or almost the same. Check the bug thread and see what you think.
