Sure thing.
You have to edit both the attack calc and the damage calc and remove the power attack from both:
1d20cs>@{weapon1critmin} +[[@{bab}]][BAB] +[[@{weapon1stat}]][Ability] +[[@{size}]][size] +@{weapon1enh}[Weapon Enh] +@{weapon1focus}[Weapon Focus] + ?{Flank (1=yes)|0}*2[Flank] +?{Additional Attack Bonus?|0}[Ad'l Atk Bon]
1d6 +[[@{weapon1damagestat}]][Weapon Dmg Ability] +@{weapon1enh}[Weapon Enh] +@{weapon1specialize}[Weapon Spec] +?{Additional Damage Bonus?|0}[Ad'l Dmg Bon]
both have the power attack taken out.
Basically anything with a ? in front of it is one of the query's which pop up and the power attack is in both the attack and the damage because it subtracts from one and adds to the other.
you can remove the query for full attack as well by editing the full attack macro and changing
{{fullattackflag=[[?{Full Attack? (hit space for full attack else hit return) |0}d1]]}}
to
{{fullattackflag=[[d1]]}}
that will tell the template to force a full attack.
If you remove the fullattackflag entirely or set it to [[0d1]] you will only get the single attack; that's what tells the template to display the rest of the attacks.
If you have any further questions, please let me know. :)
