I don't want the sandwich rolls I baked to be used as hotdog buns
Do you have other uses for those sandwich rolls?
I use them in my kitchen for making sandwiches fit for a queen.
It is understandable that you want to use the sandwich rolls the way you intended. You made them so they are yours for your use.
They are so soft and fluffy, pictures don't do them justice.
Then I am happy for you with your sandwich rolls. It's definitely okay to use items for their purpose, but I hope you're not doing so to be selfish, and I hope you would also share your soft and fluffy sandwich rolls to other family members and friends so that they could enjoy them as well.
