Radare2 Frame Pointer Optimization

[Hollyw00d]

How do I rename local variables in r2 when the local variables are relative to ESP and not EBP.

I try

>afv esp+0x14 AgeVar int

but it instead creates:

; var int AgeVar @ ebp-0x14

MOV EAX, 0xAAAAAAAA
MOV [ESP+0x14], EAX
XOR EAX,EAX
PUSH EAX
MOV EAX, [ESP+0x14] # EAX == ???????, not this is not 0xAAAAAAAA
