To make the pet actually pick excatly what you wan't do like we always do like in mbot and Sbot, CLOSE the PET in your silkroad make it OFF then go to your bot - Advanced and choose all the stuff you wan't the pet to pick then press Save & Exit and start bot.
Note: The only reason why you close pet in game is, when you put it OFF the bot can handle the filter better without the pet interfere in game when it's on, I hope it make sense.
