## Rational
Some accounting moves are created automatically or with a document that does not have the analytic selections. For such moves the accountant has to create manually the analytic lines. This can be painful when there are a lot of moves and when those moves are kind of recurring.
## Proposal
We propose to add a mechanism based on `MatchMixin` design pattern that will be triggered when a move is posted and if the move does not have any analytic lines defined.
The default criteria will be:
- account
- journal
- party

I’m not sure if this should be in the standard `analytic_account` or if a specific module `analytic_account_rule` should be created?

Indeed the implementation requires very few code, so it will not bloat the analytic\_account to have them.
