FF 14 can use /assist this key?

just want to set macro for box armies
however , seems the game cant use /assist key
what i use to make my box char work is:

Team : Tank 1 Tank 2

tank 1: no need ass ..just 1/2/3/4..for dps.. easy

tank 2(ass tank 1 dps)

/F2 (means target Tank1)
/T ( get Tank 1 target)
/1 (dps)
/2 (dps)

any simply way to make box ass tank1 or there is other key represent "assist" key? thx a lot for help

(in EQ 1 box very simple...just send /ass tank1 then /cast 1/2/3 can keep dps )

I use or you can use targeting macros for marking targets and targeting the marked target with your dps

/target "Full Name"
/assist

for the marking and targeting macro for signs there are samples in your macro menu ingame sorry loged off already =P

thx a lot for reply
I forget to make " " when typing the target name
macro work now

thx a lot
