Update estimate template depending of a customer field

Update estimate template depending of a customer field

HI,

We have a customee fields named Business Unit. Depending from the value, the template to be used for an estimate should be selected and no the default one. We notice our sales often forgot to change the template.

I thought of a workflow, which would trigger a deluge script. But I can't find a way to update that template when the record is created. Any clue ?

Regards
