PURCHASEORDER_REFERENCE_PATTERN - can it be changed to be less strict?

[wafflecrate]

Hello! Still getting to know this awesome app. I'm trying to edit the PURCHASEORDER_REFERENCE_PATTERN entry and am having two issues:

1. My current reference pattern is set to: PO {ref:06d}. So it generates PO 123456. What change do I need to make so there is a dash between the first two numbers so it generates: PO 12-3456?
2. Is there a way to make the PURCHASEORDER_REFERENCE_PATTERN less strict? Because I have a bunch of old PO numbers that follow this format: PO 12-345. But at some point the company ran out of PO numbers and had to add another digit to make it: PO 12-3456. But Inventree will only allow one format or the other. Is it possible to reduce the rigidity or strictness of the PO number reference pattern so it allows users to free type it in without giving you the error "Reference must match required pattern: PO {ref:06d}"? Image attached of the error

You could make the required pattern simply PO {ref} and remove the width requirements

You can also add # or ? to the pattern, so you have a few options:

Pattern	Example	Note
PO-12-{ref:04d}	PO-12-3456	The reference number is 3456, the 12 part is fixed and only "cosmetic"
PO-##-{ref:04d}	PO-12-3456	As above, but two numbers up front can be chosen freely
PO-??-{ref:04d}	PO-A1-3456	Allows other characters as well (also including spaces
PO-{ref:04d}?	PO-12345, PO-1234	You can enter different lengths, but the reference won't include the fifth digit, ie both examples here have the same reference. Would not recommend this.
