I don't see a function to help with that, but it shouldn't be hard.
To help you see every function, turn on Standard Stack Frame option.

The basic functionality (in 32bit Windows code) would be like this:
(written off-the-cuff, so may be some tweaks needed)
	First, for reference: How a StackFrame is contructed:

FunctionEntryPoint:
	push	ebp
	mov	ebp,esp
	sub	esp,16	;16 bytes local variables
	other code
	mov	esp,ebp
	pop	ebp
	ret

How to walk the stack:

	DWORD * pointer;
	DWORD	return_address;
	asm	mov	[pointer],ebp;
Again:
	asm{
		mov	eax,[pointer]
		mov	edx,[eax+4]
		mov	[return_address],edx
		mov	eax,[eax]
		mov	[pointer],eax
	};
	printf the return address
	if( you_want_more_data )
		goto Again;
