I introduced a new client to Manager yesterday he has many feature requests but I would like to first talk about putting a separator between line items in creating vouchers.
They were using excel to issue invoice and they separate their line items into sub totals and also give each group a name.
They said it important for their clients to see.
I therefore request for a separator which will bring a sub total and hopefully a title for the separator so that all items under that separator could be considered as a group line items.
As for labels, there is no data structure or label by which to group or name them. Nor can there be any subtotal, because only a subtotal for the entire invoice is calculated.
