How to Kalista?

Hello everyone!

I need some help in a lane scenario.

For example, i have a problem when i want to hit enemy CHAMPIONS behind a minion wave with auto-attacks. I start a trade sequence by attacking the enemy and trying to passive my way towards the enemy. The problem that i have is when i press SHIFT + MB2 to be able to jump around my CHAMPION switches targets and IT WILL ATTACK MINIONS instead of my desired target.

What i want is to know if there is any setting that will prevent my champion to attack minions on a SHIFT + Attack command.
