Is this what you mean? Not sure what you mean about ignoring circle/cross..maybe those are marks that can be assigned?

This should add the chain 1 mark to the mouse over, target it and finally add the party text. I left out a particular attack as you may want to pull with a certain attack sometimes while other times just run up to it and use some other special action.

/mk “Target to Bind 1” <mo>
/target <mo>
/p “Please attack Chain-1 marked” <t>
