There's no out of the box solution, so you would need to create a custom solution.
Client Libraries and Web Resources Client Library are defined from the editable template's page policy. Once configured, the page policies are stored in the /conf folder, where your page will be cq:template will be referencing. With the reference, you will be able to access the absolute path of the page policies, where you can access the Client Libraries and Web Resources Client Library set values.
For displaying values to the page, one way you can achieve this is by creating a custom data source (so your configurations can be viewed from a drop-down; this is for view only).
@sreedobe I understand that you are trying to overlay/override Page Properties tabs. But can you please elaborate the use case, because ideally, we dont overlay entire tabs/fields. We will just extend or add new tabs to it.
