Currency Symbol in Field placed in Dialog popup

Hi all,
I have dialog popup that show sum value of specific fields in marked Timesheets.
This dialog is open in List View.
Is there any easy “way” how change symbol currency?
Link field currency is not available due to list view.

I have tried something like this (set options to currency symbol), but it does not work, unfortunately :frowning:

            label: 'Base Price List Amount',
            fieldname: 'base_price_list_amount',
            fieldtype: 'Currency',
            default: data[0].custom_price_list,
            options: 'USD',
            read_only: 1

The field have still default currency symbol.
Thans for any help in advance.
