Overwriting Saves

[EdgeSloth]

I think I tried to ask this earlier, however I am going to clarify as the issue was not fixed. How can I use the bot so that it can play from a previously saved dbj and add on to it, so I can train it in sessions? I am teaching to play a level named Lunatic Doom Machine, so when I went to start it up I put in dashbot 00100110111 LunaticDoomMachine1.dbj. I expected this to access the previously saved LunaticDoomMachine1.dbj, which could get to 19%, however upon restarting, the bots progress had been wiped clear and it started from ground zero. How can I start it so that it can access a previously saved .dbj AND keep training off of it, as it always resets itself every time I end the session.

EDIT: Is this even possible, and if not I would love to see this added in the future as it would enable the bot to beat levels that would take a very long time.
