Importing an .aspx masterpage built using C# in Visual Studio

Binoj1

Is it possible to import a .aspx masterpage built using C# into an interwoven branch/work area so that new pages can be created off of that template.

This is very much possible in SharePoint. Wanted to see if the same can be done in Interwoven teamsite.

Please share your experience if anyone has already done similar work.
