Scale / resize a model in Z-Suite --> Wall thickness?!

Hi together

I don't know if i post in the right forum but i have a simple question and i don't know how to to that.

So, the model is a rose (attached to this topic) and i printed this out in various sizes (the quality is very amazing with the M200)

If i resize the model bigger, the wall thickness get bigger and so the Z-Suite print more lines/material.

How can i resize the model, that the wall thickness are the same as the original?

Is that possible and with which software i can do that an how?

Thank you very much
