After creating a user field in the auxiliary storage, how can I populate this field with a default value? Normally I'd do this in the attribute table with "Update All" or "Update Selected", but the auxiliary fields aren't available in the pulldown menu. The same is true in Field Calculator.
I've also tried Select All, and then Edit->Modify Attributes of Selected Features. I can enter the default value in this dialogue, but when I click OK the fields do not actually change. I get the same result if I try to enter a default value in the Attribute Form editor in Layer Properties (and I've selected "Apply default value on update").
