Spellcast action once?

Sorry if this is wrong location for post..

Is there a way to use a job ability once after engaging a monster, i get annoyed with having to deploy my automaton every fight and am hoping i can use spellcast automatically do this..

<rules>  
        <if status="engaged"> 
            <command when="engaged|aftercast">input /ja "Deploy" $target </command> 
        </if> 

this keeps repeating deploy since i am engaged, is there a way to tell it only once per engage?

<if spell="autoset">
    <if status="engaged">
        <command>input /ja "Deploy" &lt;t&gt;</command>
    </if>
</if>

Thank you again Arcon, sorry i'm still trying to get a handle on the spellcasts.. but if you read this i have another question/issue that you (or anyone) may be able to help with.

Im using this for trash monsters to avoid having to remember to put up manuevers..

			<if status="engaged">
			<if notbuffactive="Ice Maneuver">
				<command>input /pet "Ice Maneuver" $me</command>
			</if>
			<elseif notbuffactive="Dark Maneuver">
				<command>input /pet "Dark Maneuver" $me</command>
			</elseif>
			<elseif notbuffactive="Light Maneuver">
				<command>input /pet "Light Maneuver" $me</command>
			</elseif>
			</if>

Everything works except that while not all three are up it keeps trying to put them up, and this locks being able to use any other abilities till all 3 are up.

Is there a way to have it check if the timer is ready or add a delay equal to the recast?.. I tried adding wait 12; but it crashed the system, maybe my positioning?
