check amounts in specific accounts

[christian]

I've got an account, in which there is just a limited number of valid amounts
being booked. To prevent incorrect amounts from being booked, I thought of a
check through ledger.

I thought of 

--- myledger.dat
account expenses:limitedamounts
    check amount == {1|3|5|7|11|13}

2013/01/13  payeeA
  expenses:limitedamounts  5
  assets:checking

2013/01/13  payeeB
  expenses:limitedamounts  6
  assets:checking

---/myledger.dat

ledger -f myledger.dat --pedantic reg

would yield a errormessage for payeeB, because the amount isn't declared.

Is that possible with ledger?


thx,

christian
