Polish swirls local

Last weekend I spend 2 days polishing my car. My car is 1 year old and I washed it always with the 2 Bucket method,so the paint was in good condition. There were a few swirls that I managed to correct with Menzerna Fast Gloss 500 and I finished the whole car (BMW) with Final Finish 3000. The gloss improved (even tough my car is just 1 year old) so I'm happy with the result.
Now my question:

Can I polish the few swirls that appear on my car in the future locally,so without polishing the whole car? Of is there a chance that by doing so I will get differences in gloss on my car?

Thank your for your opinion!
