Like others, I tended to add appropriate Corbetts on to Munro days. I also added on some Grahams to both esp when they were en route. However, there were days when I bypassed a Graham or two, e.g. because of bad weather or just couldn't be bothered, as I never planned to finish the Grahams....may come to regret those decisions
As to the Corbetts, while there are some notable multiples, you'll find them harder to link up with many more singles than for the Munros. Took me about 25% more hill days for the Corbetts than Munros. Accept that you're likely to need many more away overnight trips unless you live near them or are happy to have long drives for a single hill. I found that planning Corbetts groups in an Excel workbook helped; building in distance and ascent calcs from my own experience allowed me to plan multiple single hills per day of a trip with driving in between.
Above all, they can be more challenging, frequently steeper and more widely dispersed than the Munros but arguably more enjoyable. Best wishes.
