worksheetfunction through vba

I'm trying to create a simple function in vba, which are to be used by others also.

Function ATP(test As Integer) As Integer

    ATP = test

End Function

If possible it would be great if the users, when using the function in the excel sheet, could see the the arguments needed ("atp as integer" should appear once the user starts writing arguments). In know this sort of help is available to users for standard excel worksheet functions.

Can I also make this available to my own function?
