Adding a research requirement to Items that you can purchase?

[KyronStarkiller]

Is it possible to add a research requirement to Items that you can purchase?
For example can I create an research project "Advanced Training" which would then allow me to hire a special forces soldier.
Or another thought would be research "Titanium/Kevlar Alloy" then be able to buy Body Armor.

Not in the vanilla game, but you can do it in OXCE and OXCE+ versions.

Ok that's cool thanks for the rapid answer.

This is definitely in vanilla: https://github.com/SupSuper/OpenXcom/blob/master/src/Basescape/PurchaseState.cpp#L200

Oh, sorry for the mislead! From what I understand now, OXCE only allows you to set a different research for buying than for using.

Well I will give this a try and see how it goes.

Thank you SupSuper and Solarius Scorch!

I was able to successfully test this modification. By adding a starting research project (Improved Avionics),  which leads to (Avalanche System).
The Avalanche Ufopedia, and the buyable launcher and missile disappeared from the list. Until the (Avalanche System) research was complete.

That was exactly what I wanted.
