How do I create a relative selection for 'My Country/Region'?

[MichaelaL]

Hi everybody,

we have a report on the C4C object 'assignments' which we want to send out via a broadcast with weblink to a defined set of users. Since the recipients are from different Service Organisations, we want to have a default selection which only shows the relevant assignments for the respective user's Service Organisation. However, since the underlying Data Source 'Service Assignment' does neither have 'Service Organisation' nor 'Sales Organisation' as an available characteristic, I cannot use the relative Selections for Service/Sales Unit. 

We could identify the user's relevant assignments also with the characteristic 'Country/Region', so I'm wondering if there is a possibility to design our own relative selection which then allows to select for 'My Country/Region'.

Thanks,
Michaela
