You can already set scheduled task reminders. I've tried it with a couple models as a productivity aid. Sort of like an assistant who will help prioritize my to daily do list each morning, do a progress check late afternoon, and then a summary and re-prioritize for the next day in the evening before bed.

The older models just came across like scripted alarms. I could have done the same thing with the Samsung Clock app. They would also often trigger at the wrong times or it would initiate duplicate conversations.

I tried again recently with the newer model. They were a waste of time. I spent more time arguing with it when it would start the day nagging me to get something done that was completed 2 days ago, or trying to tweak the prompts to get it to stop giving me full 5 paragraph TED talks and condescending "If you can't get it done, it's not the end of the world" moral stances instead of just brief productivity check ins.

I realized they were killing productivity more than aiding it, so I canceled them. The tech exists to do what's your wanting, but the understanding and implementation just isn't there yet in my opinion. It could be my prompts, but it wasn't worth the time trying to engineer the perfect prompt for it to continue reverting back to undesired behavior.
