Hello, in custom cabinets, the replacement of handles can be done individually/multiply/all at once according to your needs. Taking the cabinet as an example, the operations are as follows:

1. All at once replacement: Right-click on the wall - All handles - Click Replace, and select the corresponding handle style;

2. Multiple handle replacements: Press Ctrl and click on the door panels that need to install handles, right-click - Handles - Click Replace, and select the corresponding handle style;

3. Single handle replacement: Select a single door panel, right-click - Handles - Click Replace, and select the corresponding handle style.
