How to use fiscal year tag in sequence

A sequence can be made to use the following tags
The tags below can be used as a prefix or a suffix

  • %YYYY : Full Year (2017)
  • %YY : Year (17)
  • %M : Month (1, 2, 3, …)
  • %FM : Full Month (01, 02, 03, …)
  • %D : Day
  • %WY : Week number

However, it would be good to have a fiscal year tag or a tag like %FY with just two numbers ( like 17 for FY 2017-2018 ). We have fiscal year from March till April of next year. So changing of civil year changes the sequence for the fiscal year.

Is it possible is any way, via script sequencing, that fiscal year can be set in sequence and sequence can be reset as per defined fiscal years ?

Is there no way I can use the fiscal year in sequencing ? I suppose this could be good feature request in upcoming releases. With fiscal year sequencing, legal naming compliances of invoices etc. could be easily maintained ( they are supposed to follow a same sequence for a financial year ).
