When using this mod to build my last megabase, I found myself constantly setting certain values to the same values, particularly Limit Trains, Provide Stack Threshold, and Request Stack Threshold. Since I was using 1-2 trains without stackers, I was constantly setting these fields to 1, 80, and 80 respectively.

Being able to configure the default values of all fields in the combinator, especially on a per-map basis, would've made my life significantly easier.

There was a related ask for default stack threshold values also. Let me see if I can come up with something that doesn't interfere with the existing intent of the mod.
