yes and no. Yes to show amounts in the currency you want to show in a schedule based on calculated parameters. For totals it will not show the new unit symbol. Here is a thread on it with screenshots and examples. https://forums.autodesk.com/t5/revit-architecture-forum/is-it-possible-to-add-a-new-currency-format-in-this-unit-say-qar/td-p/6361383
Also I was thinking you could just use a parameter to have a prefix with the new unit and then use a known currency to calculate from and do the exchange rate difference to get it to convert to the currency you want it to say. But again I fear it will only show the number without the total. The problem is that you need to be able to access the unit symbol, and there isnt anyway to get to that through normal accessible ways, maybe its possible through Dynamo you could get at the API and add it there.
