Allow creation of security rules for data that does not exist yet

[joeshepper]

Creating security rules within the Data Security menu for Elasticubes only allows you to assign users access to values to that are already in your data.

If I am creating a rules for user visibility of e.g. individual 'store references' and a new store with reference '1414' is added, I can't create a rule for store 1414 unless it is already in my data. Could there be an option to manually specify the value, rather than having to select a pre-existing value?

(I am aware this possible to add via the REST API, but this is a bit fiddly for frequent small edits).

We have the same problem.  We want to create security groups, etc for new tenants, but we can't apply the data security until there is at least 1 record that meets the criteria. 

We used to be able to do this, but an "enhancement" or "bug fix" broke our ability to do this.
