use ida python to add a remark when calling a function using register

Question

I want to add a remark for all non direct function calls. e.g. say i have

mov EAX [functionEP]
call EAX

Assuming i have many such calls to various functions, I would like to run the debugger and every time there are calls to such function add a remark which states the real call address/function name so that it will be:

mov EAX [functionEP]
call EAX ; functionName

Is this possible?
