Remove older possible matches

Since Zoho Books only allows new users to import transactions for the last 90 days, we had to go through and manually enter all transactions since the beginning of the year.

Now whenever we reconcile transactions that show up under Uncategorized Transactions, they show all of the older transactions as possible matches.

How can you remove the older possible matches? Or, can you set a default filter that whenever an uncategorized transaction comes up, it won't default to all of the older possible matches?
