When a report is added to a project dashboard update the grouping (sum) column to the project's currency and not the system default currency. Example below.
Why is this feature important to you - When a user is needing a sum of multiple currency fields on a project dashboard report it can be confusing to view the project currency and the system default currency conversion in one report.
How would you like the feature to work - when a report is filtered to a project dashboard the grouping sum it will align to the project's selected currency
Current Behavior - the report grouping is shown in the system's default currency. If the project's currency is different it will convert to the system default currency and convert the total.
