JTD Issue in P&L Entries

Summary:

The client posted entries last year with the journal type as JTD. These entries were subsequently reversed in the following year at the same intersections. For example, an entry for Net Income Movement was reversed in the following year under Net Income. However, when they post a new entry in the current year, the amounts are netted off with the reversal balance. Instead, the client requires separating these amounts: the reversal amount (automatically reversed) and the new entry.

Is there a way we can achieve this through a custom rule?

Cell E18 represents the reversal value in the following year. However, when a new entry is posted, it gets netted off.
