Marking/Pull Macro question

[Thaliss]

I am looking for a macro to mark targets 1/2/3 using only one slot.
As I play on PS3 the less you use space the better

Thank to this link http://ffxiv.consolegameswiki.com/wiki/Commands in came with the following solution :

Leave one slot empty in "crosshotbar 1" - I will use "slot 1" (L2+left arrow)
copy "crosshotbar 1" to "crosshotbar 2" and "crosshotbar 3"

Macro crosshotbar 1 in "slot 1" (L2+left arrow) :
/mk attack1 <t>
/crosshotbar change 2

Macro crosshotbar 2 in "slot 1" (L2+left arrow) :
/mk attack2 <t>
/crosshotbar change 3

Macro crosshotbar 3 in "slot 1" (L2+left arrow) :
/mk attack3 <t>
/crosshotbar change 1

I haven't tested yet as I am at work. Maybe a "/wait 1" will be needed

There is the "/crosshotbar set [Action Name] [hotbar number] [Slot Number]" command.
It sets an action at a specified slot in a specified crosshotbar.

That would be helpful if "attack1" was considered as an action or if a macro could be considered as an action.
For information crosshotbar slot are numbered from the left to the right in clockwise order (L2+left=1 ; L2+up=2 ; L2+right=3 ; L2+down=4; etc...)
