Select Structure Field Based on Variable

Let's say I have a structure with multiple fields structured like this:

Structure.A = 5;
Structure.B = 10;
Structure.C = 30;

If I have a variable:

Field = "B"

Can I select the field B in the structure and set it equal to a new value? When I run this code, it creates a new field called "Field" instead of selecting the existing one from the value of Field.

Structure.Field = 15;

There is special notation to access structure or class field using parenthesis () of input string

Structure.A = 5;
Structure.B = 10;
Structure.C = 30;
Field = "B"

Field = "B"

Structure.(Field) = 15 % this updates required field without adding extra field 

Structure = struct with fields:
    A: 5
    B: 15
    C: 30
