There are options, and there are opportunities for promotions and career progression, especially for the supply chain side of the business!
Diageo is extremely performance based, you don't get the politics here that you do elsewhere when it comes to promotions and succession planning. If you are performing in your role and have made an interest in something else clear to your manager and HR, you will have every opportunity to get that job.
Skills, the company is the perfect place for some one that can learn quickly as there are constantly new opportunities to progress of change roles. Either within your team or to a new team
