Duplicate EXTRAS or make them available for multiple services#1306

It would be very helpful to be able to create EXTRA services and making them available for all services so you don’t have to re-create them over and over again. EG: Service: Men Hair cut > Extra service > Coloring.
If I want to have the extra service ‘Coloring’ available for Wonam Hair Cut, then I have to create this again. Instead I’d love to be able to re-use the previous extra service. Makes sense?
