i am suggesting a hack that would provide the ability to change the values in the scoreboard.
it could look like this in the settings of the hack, e.g. "Scoreboard value" (like "ExampleSMP", or the exact value of server's currency or playtime "$1234" or "1d 23h". if possible, make it track the value even if it changes) and "Custom value" right under the scoreboard value text box, that will change the scoreboard value to whatever is set in the custom value. could be one pair of the two things i mentioned by default, and a singluar plus button under those 2 hacks to add another modifier for another part of the scoreboard.
(i don't know if i explained well enough, but you get the idea)
