Modenbill Template Modification - adding package attributes to modernbill client interface

This is a fairly simple straightforward project. I'm attempting to recall 2 package attributes from a package then display them where I want on the ShowPackageDetails page. Files that will need to be modified in Modernbill: lib-themes/xpreloaded/app-modernbill-client/templates/packages/[login to view URL] app-modernbill-client/include/lib-action/packages/[login to view URL] Attributes that are trying to be recalled: I'm attempting to recall packageUserName and packagePassword (attribute names) from the package that has been selected to be shown on the ShowPackageDetails page. I would expect this should be very quick for any PHP coder whom has a bit of experience with the modernbill or pleskbilling package.
