could you please make the project numbers adaptable like the numbering of the billing module?
So to have a prefix and a postfix?
And maybe to have a configurable numbering format like A1-PJ 10001-001 (where -001 is the subproject).
And maybe to define different number ranges, e.g. one for internal projects, one for client projects and one for supplier projects?
And each subproject could get the following numbering format: A1-PJ 10001-001.
And the second child would get A1-PJ 10001-001-001.
So you know, where the Subproject belongs to.
And please consider to make the number of digits for subprojects (-001) configurable (e.g. one company need only 1 digit, others, need even more than 3 digits...).
