Setting GTK Dialog default answers

[cjsmall]

I'm sure that due to an upgrade from GTK2 to GTK3, the default responses (i.e., the active button) when a pop-up dialog displays changed between GIMP 2.8 and 2.10.  Even after a few years, these changes still bother me.  Is there any way, external to the GIMP code itself, that the default responses for a given dialog can be set?  I'm hoping that there is some kind of external file where this might be set.  I'm just not familiar enough with the GTK internals to know if this is possible or not.

Thanks for any insights.
