setup modx subdomains on localhost with windows and wamp

I have modx site with multiple subdomains. for a development purpose i want to create dev environment on my localhost with windows 7 and wamp. i want to set subdomains like sub.mysite.com, sub1.mysite.com. I know how to create virtual subdomains which maps to different directories, How can i map my subdomains to modx subdomains ? is it possible with modx ?

I don't fully understand the question.

If you want separate MODx sites on these sub-domains but within the same MODx install you can create a different context for each sub domain.

Take a look at this (it might actually be what you are after): http://rtfm.modx.com/display/revolution20/Creating+a+Subdomain+from+a+Folder+using+Virtual+Hosts

Ohh i am sorry my question was not that much descriptive. Let me explain again, I have live site running which contains multiple sub-domains (6-7) like sub1.sitename.com, sub2.sitename.com. Now i moved it to localhost for some development purpose and now i want to make it work on localhost with all subdomains. so in this case how can i see page for "sub1.sitename.com" when i enter sub1.localhost in browser.
I think i have to mal my "localhost" to some "dummySiteName.com" using apache, then i have to make changes to contexts setting.
Actually my manager panel isnt working (core/model/modx/processors/system/registry/register/read.php does not exist) so i cant check if it works or not, so i am asking and confirming if this will work or not...Thanks in advance.

This works on live servers so you might get it working by changing your host file on your pc to direct to your localhost for the sub domain.
