How to Restrict Manual Account Entry in Adjustment/Write-off Match Type in ARCS?

In EPM ARCS, when we manually match the transactions with variance a write off/adjustments will be created , users currently have the ability to manually enter accounts when performing adjustments or write-offs.

We’re looking to restrict this behavior so that users cannot manually enter accounts and are instead limited to predefined accounts.

In the adjustment type we would like to make the account fields to be non editable.
