Requirement to Show 13 Prior Ending Balances in ARCS

Hi Team,

In the Account Reconciliation screen, we can see period‑ending balances only for 12 months (April 25 to March 26).
The client also wants to see the prior ending balance for March 25, but I understand that adding an extra prior period balance in the reconciliation screen is not possible.
As an alternative, can we create a custom dashboard for an individual reconciliation to show 13 prior ending balances?
In the Properties tab, we can select Prior = 13 and set the File Type = Line.
What should we select in the Layout – Legend / Series section?

Regards

Vinod
