It will depend on if the prosecutor thinks it's worth it. Often it won't be if they already got a guilty on enough counts to add up.

If the prosecution decides to pursue it. They may very well decide that finding her guilty on 4 of 11 counts sends a strong enough message.

It's not about sending a message, it's that the sentence will almost certainly be carried out concurrently. That means even if she is found guilty of the remaining counts it won't result in any additional time served.
