Default form values are such a huge time saver for many of my clients.
Today I noticed that we do not currently have the ability to select multiple linked records by default, similar to how we can select multiple multi-select items.
In my pictured example, I’m able to select multiple options from the drop down menu on the form field itself. But I am only able to select one option for the default value.
Back to bump this please 
I seem to be the only one really caring about this one, but this would be super useful. Just ran into another use-case where I’d like to pre-select multiple linked records but can’t 
so bumping once again 
@darragh Also bumping this one as I now have a somewhat urgent need for this.
In my case, I need to have a default filter populated from a collection field.
I have a field called “Default Division Filter” on my User table, which links to our internal divisions. A seperate field controls their Access to filter on other divisions, but users want everything pre-filtered based on their primary scope. This field is essentially a user preference that set their default filters across multiple elements.
When populating a dynamic default value for a quick filter, we can only select linked fields, not collections.
