sourcemap locations wrong?

[sroe]

Hi,
using this configuration for example:

options:{
screwIe8: true,
sourceMap: true
},
files: {'<%= deployment_path %>/file.js': [
'<%= src_path %>/scripts/file1.js',
'<%= src_path %>/scripts/file2.js',
'<%= src_path %>/scripts/file3.js'
]}

Is it possible to have the sourcemap as 1 file with 1 path information in it? At the moment I get 3 path informations inside the file.map.

Another question: Would it be possible to have a source file generated with stripped comments and that file used as source file inside the map file?
I'm trying to achieve this 2 goals for a while now with no success 😒.
Regards
