Support for Namespace Prefix

I'm trying to migrate an old COM add-in to Excel DNA but there are several thousands of worksheets (from dozens of users) who have the old COM add-in. After migrating ALL the functions to Excel DNA (by retaining the function name and signatures) the sheets built with old COM add-in shows the functions as .customFunction(), while Excel DNA add-in shows the functions as customFunction().

Is there any way in Excel DNA to mimic the function (like the COM add-in function) with custom namespace prefix to every single function?

*Asking every user to update all their worksheets is one hell of route that I'm trying to avoid :smile:
