I would like to be able to set the Always One Selected Value flag on a field as a part of the load script, rather than having to configure only in the front end. An alternative that would work for my environment is to be able to have that configuration move as a part of a binary load.
I am responsible for setting up data models that will be used across multiple apps that other people will be developing (they do a binary load of my data model and then build sheets). In my data model there are some fields where the appropriate usage of them is to set "Always One Selected Value", however this has to then be set by the people who are developing front ends in every app they create.
If this configuration goes with a binary load then by default those other developers get the setting, and if it can be configured as a part of the script I can share a sub with them that they can run in their script after the binary load to achieve the same result (and very simple to audit that it is being done).
