Select an instance to be moved in the floorplan, click on Locking to access the following possibilities:
Lock in target allows to select a target for the resource to be placed directly into the floorplan
In the above example, the instance selected is LOGIC|lut_2, originally placed by default into the TILE[17x6] as seen on the location field near the instace in the left menu of Selection widget
In the right menu of Selection widget, dedicated to Locking actions, the target location is dynamically adjusted as the cursor is moved into the floorplan
Once the target location is set for example in TILE[18x6], click on it through the floorplan and the instance will be automatically moved into the targeted resource and the location information in the instance list will be automatically updated as shown below

The target for a resource previously placed can be edited and modified using Unlock button:
the previous target placement will be relaxed
you can reuse Lock in target to change the target resource as desired
When you want to fix a target resource for an instance already defined by the tool in order to be kept through the whole Place & Route flow, click on Lock in place to permanently fix the target for the selected instance
