I did the same with about the same amount of accounts and it took me the better part of a Saturday. Even if you were really slow and needed five minutes per account, 200 accounts would still only take about 17 hours.

I don't think that's a lot of effort. You could easily spend that time fixing something around the house or garden, which often might not have nearly as big of an impact on personal agency.
