Hi Jason,
Yes we have explored this but would be too much work getting 'all' the data from SC request to SDM. having looked into some of the webservices I couldn't exactly see which one in SC gives me the data in the request items. Or if I could call the webservices using a single method to get ALL the data.
I think this would be a good idea as a enhancement suggestion to be able to enable/disable OOTB. We frequently find customers are looking for something like this.
