With FCC and Reporting/Narrative Reporting, there isn't such a function. But there's still the same need. I filed an idea lab submission to request the function. I thought I (and my clients) was out of luck, but then I thankfully ran across a simple solution, and it's built in!
When building the report, look at account FCCS_CSTATUS FILTER. This account just doesn't give you some number that you have to convert - you get the proper text status. Along with specifying the account, you have to set the point of view to FCCS_No Data Source (which isn't used often) and FCCS_No Movement. The rest of the point of view should be normal for other data retrieves, but the intercompany and custom dimensions should be set to FCCS_No Intercompany or No custom.
And being an account, this means that the calculation status can be pulled into Smart View with either ad hoc or functions, which is a big bonus.
