Going online with multiple PLC's in Automation Builder

Hello,

we are working on a project in Automation Builder with multiple PLC's. This is working fine, but is seems impossible to go online with other PLC's then the upper PLC in Automation Builder. Going online in Automation Builder instead of codesys can be usefull for error messages from the cpu etc. If we select the third or the fourth PLC and we click online then every time the first PLC goes online and not the third or the fourth.

We know the existance of the download manager, but this is only usefull for application downloads and firmware updates.
