Dear All,
We did this as a project for a client and it is not as easy as it appears from the guide, dispositions appear in a number of places in the UI and the guide is a little optimistic, the implementer needs to be quite proficient and the guide is missing quite a few details. Here is a link to the component we did, no reason you can’t do it you yourselves (or get it from us) at least you can see from this page the UI that requires touching.
Best Regards,
Simon
