Analytics report on proxy chaining.. no of call to a proxy and from a proxy

[#1]

I want to capture reports on the number of calls made to a proxy and from a proxy. Selecting Target URL as dimensions I can get from which proxy which target url is called.

But I need in both side, i.e call to a proxy and from a proxy. Let me know if anyone has done similar kind of work and also I want to know if this scenario is a valid possible scenario to achieve?

If you select the apiproxy dimension, you will get all calls made to proxies. If you select the target URL dimension and filter out the ones which are not proxies, you should get the calls made from a proxy to another proxy.
