Question - /squelch

[Slade the Magician]

I was tweaking a macro I've used for my mage, and found that while targeting and assisting the MA it's easier to /target clear if the NPC targeted is above 99% health. This has several (laziness related) reasons, as i could always fix the targeting to ensure I get monsters withing a certain range or whatever. ANYWAY, so my Mage would get stuck just "assisting" my puller on a monster I never pulled, just at one point targeted in an attempt to add it to the swarm I was aggroing. To fix this I added a /target clear line in the beginning of the waiting for monsters line of my script. What I noticed is an echoed message about clearing target. While I appreciate the message, I know it's happening so would like to squelch it. How exactly would I do it properly? Just have its own line somewhere?

/squelch /target clear

Or something else? Thanks for the info folks!
