Ability to fetch Course Summary file via core_course_get_courses webservice

I have been trying to fetch course summary file through web-service externally.

i am using  "core_course_get_courses" but it doesn't return course summary file. See the below returned information.

Can we have this ability inside this web-service or is there any other option for this? can anyone suggest a possibility to get course summary files externally using webservices?
