Building Upgrade Cost slider

[almagnus1]

I would like either information on how to code (or someone that wants to just write it) a plugin that does the following:

Provide sliders to adjust the upgrade cost of all the buildings at KSC, with the default values set to their values on normal difficulty.

This way I can jack up the difficulty by playing on hard mode, use mods like DRE, RemoteTech, TAC LS, and FAR to make it harder, and not have the grind increase exponentially - as I want reasonable progression, but not soul crushing grind, especially with added cost of building the RemoteTech infrastructure and accounting for TAC LS related expenses.

Take a look at Custom Barn Kit; if it doesn't do exactly what you want, it'd be the most likely candidate to add a feature
