Including an amount in one's zakaat calculation that one set aside for sadaqah

I made an intention that a certain portion of my annual bonus will be set aside for Sadaqah and Lillah. The money is not in a separate bank account but together with my savings. I have a spreadsheet of the amount what was spent and how much is still available for charity.

Do I need to include the amount into my Zakaat calculation, assuming that I have not discharged it as charity it for a lunar year? The intention is to still discharge the money as Sadaqah or Lillah.
