How to create a custom field and set the only members of the team that can see it?

How to create a custom field and set the only members of the team that can see it? I need to create a field of Cost, and select the users who can see it. Like a private field on my issues. Is that possible?

I do not believe JIRA allows the granualarity of field level security natively.  We use a plugin that allows for the creation of secure fields that can be secured by a group via a permission scheme.  The plugin we use is https://marketplace.atlassian.com/plugins/com.coresoftlabs.secure-fields.secure-fields/server/overview
