javascript - prefix for modules getting loaded using requirejs -

my application has different modules ask files in following way :

var urlrepository = require('modules/common/urlrepository/urlrepository'); 

also modules required using following way :

require(['modules/common/urlrepository/urlrepository'],function(urlrepository){     }); 

now, suppose i've same structure in 2 folders :

    folder1     |     modules     |     common      folder2     |     modules     |     common 

is there way can define global variable currentfolder ="folder2" & depending on variable load respective modules.

i don't want change existing code inside each file. want appended before require calls.

assuming folder1 , folder2 children of baseurl directory:

to use folder1, put in main js file:

require.config({paths: {"modules": "folder1/modules"}}) 

to use folder2, put in main js file:

require.config({paths: {"modules": "folder2/modules"}})
