Well, if SFDC says you can't assign that permission to a user w/ Standard Platform License then you can't. There's a reason why Standard Platform Licenses are cheaper as they give lesser functionality.
Designed for users who need access to custom apps but not to standard CRM functionality. Users with this user license are entitled to use custom apps developed in your organization or installed from Salesforce AppExchange. In addition, they are entitled to use core platform functionality such as accounts, contacts, reports, dashboards, documents, and custom tabs. These users are not entitled to some user permissions and standard apps, including report subscriptions and standard tabs and objects such as forecasts, leads, campaigns, and opportunities. Users with this license can also use Connect Offline.
Your only workaround is to upgrade those users to a regular user license or delegate the work of CRT to a user who has the requisite permission.
