Ability to display Discount Amount with fixed 4 decimal precision in Supplier Channel Management

We would like to display the Discount Amount field with a fixed precision of 4 decimal places in Supplier Channel Management > Manage Supplier Programs > Eligible Products (Classic UI, 26C instance).

For example:

0.1 → 0.1000

1 → 1.0000

We tried using Page Composer personalization, including the Value expression and Truncate At property, but were unable to format the amount to display a fixed 4-decimal precision. The expression editor also doesn't appear to allow formatting functions.

Is there a supported configuration or personalization option to display the Discount Amount with 4 decimal places in the Eligible Products tab?
