How to increase silk size in ladder's header

[dovj]

Hi,
I want to increase size for silks in ladder's headers. Can't find settings for it. Is it possible? I am constantly switching between horses based on silks and to have bigger silks would be nice for my eyes Image linked what I am speaking about. THANKS!

I don't think this is possible but I would like also to be able to have larger silks.
