Kindly provide check box for selecting multiple service instances for attaching to an app

When ever a user creates an app and tries to attach multiple service instance to his app he has to first select and click on Add a service or bind a service , assuming Add a service is selected the user has to select one service instance at a time which has to be re-staged again b4 he can go in and select an another service to his app which is very painful and time consuming, instead if we can provide a checkbox where in he can select multiple service instances in one go and click on restage button which will restage all the services instances parallely in one go which will save time to the user, since restaging takes anywhere btwn 10mins for one service instance to be attached. now all the N service instances can be attached in 10 mins instead of 20-30mins time for 2 services..
