Ok I got another noob question.. This is my second post..

Is it possible to create let's say, 3 five-minute ringtones that we can switch back and forward whenever we wanted to,
without going through the whole 'delete this, rename that' thing everytime after the first?
For example,
Monday I want song a
Tuesday I want song b
Wednesday I want song c
What can I say.. I get bored of things quickly lol
