How to vary the "proportion" parameter - MulticlassOversampling class

[jnatmed]

Hello, I am trying to vary the proportion parameter in the MulticlassOversampling class:

I tried passing passing through the declaration of an instance of the class, but when executing it it had no effect.

I also tried in the declaration of the distance_SMOTE(proportion=0.5) method.

This is so, because the MulticlassOversampling class creates examples until it matches the majority class. However, I want to try different variants and not only create up to 100%, but 75 or 50%.
I hope I made myself understood.
