How would I go about adding a custom invoice group with format like:
ID/INV-CLIENT/M/YY
ID : invoice ID,
INV : custom text
CLIENT : initial of my Client,
M : Month when invoice created,
YY : 2 last digit Year.
when created it would look like: 100/INV-BUMA/IV/15
or can i create addional “Identifier format template tags”
Thanks
