If I have an existing installment plan with the IRS from a previous year will this years owed taxes automatically be added to that payment plan?

In a November 2021 brief released by the IRS they state "The IRS will automatically add certain new tax balances to existing Installment Agreements, for individual and out of business taxpayers. This taxpayer-friendly approach will occur instead of defaulting the agreement, which can complicate matters for those trying to pay their taxes." There is no clarification on what these "certain new tax balances" are.
