converting just 1 ASP file for an ASPX project

I'm working on an ASPX project, primarily in C#, and there's one really old ASP file from like 6 years ago I want to include. The code is rather complex so it'd be faster to have VS 2010 web dev express take a crack at converting it from VBScript to a more modern language (likely C# or VB) first than for me to go on a copy and paste rampage and fix all the syntax on the fly. Also, I don't actually know VBScript and some of those commands don't immediately remind me of a VB.NET parallel.

I don't actually have the original project file for that ASP page I want to convert either or I'd use the entire project conversion tool then just grab that one file. So is there a way to convert just 1 page to modern .NET for an existing project? I tried adding it to the project as an existing item and it color coded the code all great but our new server doesn't even support anything that old (or non-aspx extensions) so the code has to be converted. Anyone know if there's a way to do that?
