Hello,

I'd like to set a prefix to my purchase orders' reference number which is the same as the reference number of the corresponding analytic account. (All of my POs have only one analytic account matched to them.)

So for example if the reference number of my analytic account is 106020, then the reference number for the first PO paired with this analytic account would be 106020-1, then 106020-2 and so on.

Can this be done? If so, how exactly? I'm fairly new to Odoo so if it'd be solvable with a minimal amount of coding that would be just great.
