We have a TW application, running at several customer sites.
One of the main forms is a view presenting a list of records.

I want the possibility to add a default prefilter for an IAM user group. 
This prefilter will not be predefined in SF because the prefilter could be different per customer.  So this is a consultancy solution.

There is IAM, Authorization, User groups, Group preferences, Default prefilters; but here I can only select a default prefilter as created in SF. I need to be able to create a prefilter in IAM, based on a column value.

I find something that looks like what I'm searching for, but this is per user and making it ‘default’ does not seem to work. This is in: IAM, Authorization, Users, User preferences, Prefilters. Here I can define a custom prefilter using the ‘prefilter columns’ tab. Only I can't get it to default activate after loading the application. It can be manually activated though, using the ribbon.

I would like the same per user group, and the possibility to enable it by default when starting the application (when the form is loaded).

Linked question here.
