How to tell IDA that a local function variable or function argument is a pointer to structure?

Also, is it possible to do the same thing to a register. For example, if ESI points to a IMAGE_NT_HEADERS structure, can I tell IDA to automatically display appropriate structure members when accessing them through ESI+offset?

In other words, instead of this


cmp     dword ptr [eax], 'EP'
jnz     short loc_600A3233
cmp     word ptr [eax+18h], 10Bh


I would like to see this (without manually selecting structure offset for each line)


cmp     dword ptr [eax+IMAGE_NT_HEADERS.PESignature], 'EP'
jnz     short loc_600A3233
cmp     word ptr [eax+IMAGE_NT_HEADERS.OptionalHeader.Magic], 10Bh



Ta,
Boris
