My employer has us do most of the corporate training annually anyways, so in our case I don't think centralizing would be of much benefit. (There are tweaks, this year mentioning AI a bunch, but for the most part each is exactly the same interactive video thing every year.)

Fortunately they have an accessible mode which turns off all the video and audio so I just click through that, wait the prescribed amount of time while I do something else, and then take the test.
