Why not all of the modifier types are declared in modifier types?

[FilipeInacioXD]

There are some modifier types such as:

building_subsistence_farms_throughput_mult country_military_weekly_innovation_mult country_production_tech_spread_mult country_society_tech_spread_mult building_unincorporated_subsistence_output_mult building_trade_center_throughput_mult

I, more or less can understand that they are generalized

Ex: country_{type of tech}_weekly_innovation_mult

But is there a generic declaration somewhere?

I'm currently making auto-complete for a text editor and I wanted it to show me all modifier types dynamically (i don't need to upgrade it in case Vic 3 changes)
