This can be achieved by mapping Zone Parameters to IFC Properties in ArchiCAD 18.
Step 1: Navigate to the File Menu>File Special>IFC Scheme Setup.
Step 2: Locate IFCSpace on the left hand panel, click upon the New Property/Classification button. Specify a Property Set Name followed by the Property Name. Click OK.
Step 3: Highlight the IFC Property and click upon the New Rule button, followed by Add Parameters. Add in the parameters required, in this scenario the parameters that'll be added are:
Zone Name
Home Story
Custom Text (Located in Add Object Parameters)
Click OK.
Step 4: Select the Zones and open up the Zone Selection Settings, in the settings tab navigate to the Additional Tags option, pop a check into the box "Show additional tags" then choose the newly created IFC Property from the drop down menus.

Because we've created the IFC property at IFCSpace level this newly created rule will then be used for all IFCSpaces on every story!
Hope this helps.
