I've been looking for a way to internally name a sales order or quotation, but it seems that there's no such way. I have a lot of quotations regarding the same customer, with similar total prices, so it becomes hard to find the particular quotation that I need. I found a (tag_ID) bar in the quotation sorting bar, but I cant find a way how to add the tag to the actual quotation. Did any of you solve such a problem?
