Hold Targets

[injbr]

Hi everyone!

I need to know if is possible to hold targets with Injection.
I don't like waittarget, i need to cast a spell and hold this target for 2, 3 or 4 seconds then i press a hotkey and spell goes to last target or self target, like Last Target and Target Self in UO Macros.

I need this because in UO some macro keys just disappears when i close the client, and i need to do again this macros when i log on.

It is possible?

Sorry for my poor english and thank you all.
