Is there a way to change data types in all tables. For example varchar(50) to varchar(100) for every instance of it.

Dear user,

there is no way to bulk edit datatype for now. But it will be usefull for other users. We will discuss it with our team.

Thank you for your assistance,

Maybe, like a legend or template types that would be awesome.

user-defined data types ... then change 1 type and it applies to all columns using that user type. life could be so easy.
