Hi @SBencheikh! Welcome to the Community-- happy to have you here 
From what I understand, you want to track your multi-year values as their yearly totals, is that correct?
You can likely create a custom formula property to host that yearly value in a separate property. This Knowledge Base article walks you through that process. That said, do the totals of years vary from deal to deal? I wonder if it would be useful also to have an automatic calculation for the total years of each contract as well.
To our experts @danmoyle, @RSchweighart, @Jnix284: do any of you have tips or tricks for creating this kind of calculation property? Thanks!
Best,
Kennedy
