How to perform massive request on ITShop?

Hi everyone,

I'm using One Identity Manager 8.1.3 

Does anyone know if  there is an existing function in One Identity Manager that allows a massive request operation? I need to request and unsubscribe different service items for multiple emplyees on ITShop. I need to do this operation often, so requesting or unsubscribing products one by one can be really expensive in terms of time. Sometimes I also need to request this operations without using their usual workflow but only approving the request or the cancellation in self service.
So, is it possible to do a massive request operation and select if the requests will be self approved or will follow their workflow?

Thanks
