1. Click the "Working set record" plugin.
2. Choose plugin settings
In the opened window choose the settings
Choose categories of families.
Click the button to refresh the parameter sheet.
Choose a parameter where you want to record.
As a result, the name of the working set, in which the item is located, is written to the specified parameter.
