Hi Gabriela thanks for posting in the Lucid community! I'd like to understand more about the current state of your diagram and what you're hoping to achieve. To clarify are you saying that with your data import from Excel you've created some employees to start with and now wish to add more reporting into "Bob the manager"? If so you can create additional employees in new or existing tiers by clicking on the "+" button that appears next to existing org chart shapes. I've demonstrated this in the GIF below:

Or are you saying that you've already created all of the employees you need via import but need to reconfigure how they're structured and reporting into "Bob the manager"? Are you hoping to achieve a result like my example in the screenshot below?

If possible a screenshot of your diagram (or a representative example) would be very helpful!
