upon importing a document, I would like users to be forced to select a template to assign metadata

If that is not possible.

how do you all get your users to input metadata? aside from simply trusting that through word of mouth they will do as you ask.

I do know that in the laserfiche client, there is a method where you can select a default template to be assigned upon importing document. Which is a step in the right direction.

but what I would like is to force template selection on folder level.

honestly on any level because at this time it does not seem like that is an option
