You should be able to open as many accounts as you like with most of the main banks ( I have a few with AIB, so I'd assume that you can do the same with most of the others), & associate them all on internet/telephone banking, so as you'd be able to keep track of them all & set up regular or one-off payments into. They would all have different account numbers & the actual accounts would be opened in your name, but when setting them up for internet use you can just name them 'holiday' or 'car' etc. , & would achieve the same goal.
