Hello

It is mentioned by Karnataka Examinations Authority itself that the options you choose in the first round of counselling will remain same throughout the three rounds of counselling and they can't be changed for further rounds. You can reorder only higher options. The options entered by the candidate for the first round will remain same even for the second round of seat allotment (only in the higher order). The candidates will not be allowed to enter options again. Option Entry done before the first round will be the final list of options.

If new colleges are added to the seat matrix, then you can add them .Usually fresh option entry will be allowed during second round.

Hope it helps.
