How to add "-" in Web resource names

Hi All,

Problem: 

I am trying to add a new Web resource names with "-".

Problem Scenario:

I am integrating  AngularJS with CRM form, I need to add few js files with "-" in there names ex: "angular-filter.min.js". How can I add a Web resource  name with "-" in the name. 

I don't want to replace or remove "-" from the web resource  name. Is there any workaround ?  Please shed some light to get out this issue.

Error: 

Web resource names may only include letters, numbers, periods, and nonconsecutive forward slash characters.

Thanks

Jones
