[GNC] [GNC-dev] Is the import match map still required?

[flywire]

The most obvious match would be to match any Transfer Accounts in the data
to gnu Accounts, even if the result needs to be verified.

Other comments:
1) User's rapid clicks can unintentionally select the wrong account,
mapping invalid data
2) Seems there could be an opportunity for user to re-run a process to
recreate map and prune the useless matches David refers to ( dates,
connectors (a, and, the etc.), transaction amounts ?). With enough
transactions this should be pretty good.
3) I assume the table is updated with merged accounts,
