Thanks for the addition! This is a nice feature addition for those who use multiple instances of HTMLWebpackPlugin in a single webpack compilation

hi @AnujRNair thanks for the swift response. Can you make a feature release. this #15 is a little important and we do need it now. rite now we are directly including this plugin from Github for the fix.

[AnujRNair]

Done!
