Dumb brokerage firm technology must have been designed by a man
My wife has an expression to describe things that are designed poorly.
She says "it must have been designed my a man."

Most brokerage firm technology platforms are just as bad. They are a throwback to the days when you (meaning someone... I'm not exactly sure who) would walk into your broker's office and say "Hey, Jim-Bob... Buy me 200 shares of Acme Rocket Boot Company!"

Even if you are only investing in a handful of funds, and only making occasional changes, this technology wastes time and creates multiple opportunities for you (or your investment adviser) to make potentially costly mistakes.
Here's a much better alternative:
