I'm not sure this applies to your particular situation, but a general solution for proceduralizing behaviors that was discussed at minicamp (and which I'd actually done before) is: Trigger yourself on a particular physical sensation, by visualizing it and thinking very hard about the thing you want yourself to remember. So an example would be if you want to make sure you do the things on your to-do list as soon as you get home, spend a few minutes trying to visualize with as much detail as you can what the front door of your house looks like, and recall what it feels like to be stepping through it, and think about "To do list time!" at the same time. (Or if you have access to your front door at the time you're trying to do this, actually stepping through your front door repeatedly while thinking about this might help too.)

And if there's some way to automate it, then of course that's ideal, though you said you don't know when the next conference will happen so that's more difficult.

Or another kind of automation: maybe you could save the bio you wrote in a Word document, and write a reminder in it to add the edits you want... or just do them now, and save the bio for future use. Then all you have to remember is that you wrote your bio already. Which is another problem, but conceivably a smaller one: I don't know about your hindbrain, but upon being told it had to write a bio, mine would probably be grasping at ways to avoid doing work, and having it done already is an easy out.
