How do you add a new data type to schema and update all existing databases to have default value instead of undefined with Mongoose/MongoDB?

I have figured out ways to fix this, such as looping through every single data structure and updating the new data type implemented through code. However, is there a simpler way to make it so if I update a schema, I can immediately update all pre-existing data structures to default to say true or false?

As of right now, if I add a new boolean to my schema, if I check compass, there are grey spots for every single discord server in my case, besides the few that made use of the new command already and have set the boolean to true or false. The problem with looping through every single data structure and setting it's value is the people who immediately make use of the new command, and therefore, I would have to include yet another check to see if it's not undefined. How can I do this? Or am I doing it the only way possible?
