LOL, no. That would not be my choice.
You need to find out where the data is coming from. In the case of Transactions, there are 3 Tables that hold data.
Each of them has a
[Name] column. It might be that the Account Screen is using one Table, Transactions (in the Manage > Accounts section) is using another Table, and Reports are using yet another.
So the "safer" way would be to run an UPDATE statement on the Tables for the
[Name] column, while matching the exact
[Id] for the record.
The Tables are all related, so which
[Name] field is being used in which scenario is up for grabs ...
