I would like to make the invoices and by sequences under year AND month, just by setting up at the sequences under Settings => Sequences & Identifiers.

Can you please teach me how to set the sequences as expected?

== Example ==

Invoice Date: Dec 2016: INV-201612-001, INV-201612-002, etc

Invoice Date: Jan 2017: INV-201701-001, INV-201701-002, INV-201701-003, etc

== Setting 1 ==

Prefix: INV-%(range_year)s%(range_month)s-

Sequence Size = 3

Use subsequences per date_range = TRUE 

== Result 1 ==

Created an invoice dated on Dec 30, 2016, the Invoice number generated as "INV/201601/001", and the table of subsequences created a line between 1/1/2016 to 12/31/2016, and next number as 2

== Setting 2 ==

Prefix: INV-%(year)s%(range_month)s-

Sequence Size = 3

Use subsequences per date_range = TRUE

== Result 2 ==

Created an invoice dated on Mar 3, 2017, the Invoice number generated as "INV/201701/001", and the table of subsequences created a line between 1/1/2017 to 12/31/2017, and next number as 2

Many Thanks!
