Just describe it as you want it, in plain language if necessary, e.g.. Push face West abeam Stand X to let out blah blah, leave room for blah blah to park, when you taxy you'll be going to the outer at Block blah blah (OK, ok, I know it's all changed to funny numbers and funny clearance limits these days....).
CAP413 went out of the window at Heathrow GMC...it had to....wouldn't work otherwise. Just be clear, assertive and positive to achieve what you want to make it work, stuff the RTF Police, ATSD won't mind...
