Is there any way to adjust the "era" of each of the ROM research technologies? I'm using ROM and Vanilla Expanded - Tribals for a tribal start. VE allows you to progress your tech era up from Tribal to Neolithic to Medieval etc. by researching each technology in the previous era. Your research speed is reduced for all technologies above your current era.

Most of the ROM technologies are classified as Neolithic techs, which means I need to research nearly ALL of them before I can research things like "beds" - it's an unfortunate mod interaction.

How can I adjust the era of each ROM technology, so I'm not stuck in the Neolithic era for an eternity?

edit: and yes, I know about the Tech Advancing mod, but I'd rather avoid using it if I can make adjustments to the tech levels in ROM itself.
