Semi-bold font weight possible on existing Bubble font?

I am working with existing Bubble fonts and want to make it semi-bold instead of bold.

Is this possible without using a custom font which i am trying not to use? I am using many of the same fonts but with different weights.

Depending on which font you’re using, there are several weights offered in the font picker. I think this is probably the only way you’re going to get in between regular and bold, and it might not be available for your chosen fonts.
