In profit switching, I'd like to run one miner for 1 hour (and it would switch), then another miner for 1 hour (same rules but different payment address), then the first one for 1 more hour...

In essence, I need a timer. I couldn't find a way to do that. Is there?

you have to set a Time Trigger rule for a specific time, day or on a regular interval an use templates it works best using templates  an there is a rule for Profit mining .

and profit mining does have that look under the Profit Switching tab under options it lets you set some of those setting ...
