UCSB --> Business Schools?

I plan on attending UC Santa Barbara as I have been given a full ride, but it doesn’t have the traditional business major. It has economics and accounting with some business work ins.

Can someone help me flesh out some sort of plan to transfer to a business school within two years? Is it even possible from a school without an undergraduate business major? I’ve been searching for information, but I’m still relatively in the dark here.

If I complete the prerequisites and do exceptionally well do I just apply for a UC to UC transfer in two years?

Would it be better if I just went to community college for two years took the appropriate business courses then transferred to an ideal school for my intended major?

Thank you in advance for your help and advice.
