Do I need to request a modification of UCC balances for previous years with CRA that I maunally overrode? No imapact on taxes

[ba063]

In 2017 I disposed of shared rental property (50/50 with my spouse). I have recaptured CCA.  In 2015 had class 1 additions, forgot to include them in my tax return. My spouse did in hers.  In 2017 I overrode the UCC balance that was transferred from 2016.  Do I need to request a modification of my 2015 and 2016 tax returns with CRA to reflect the proper UCC balance?  No impact on my taxes, as I did not claim any CCA for both of those years.  Thank you.

It might be easier to simply include the missed amount as an "Addition" to the class in 2017.
