I need more invoices statuses (validated, billed...)

Hey guys, is there any way how to add more statuses for invoices?

My client wants to have - preorder, validated, deposit paid, billed, delivered, assembled, problematic order, cancelled order.

I found a way, that i can change the translation of the existing statuses of the orders, but i need to add 3 more.

Thanks for help, love dolibarr

preorder == validated proposal ?
