How make one faction store

Hello, first of all I apologize for the bad english but I do not know the language so I use google translator.
To which I come, I would like to achieve in some way that players only have access to the stores to the content of their faction, both in the general store, cannons and vehicles.
For example: add the MX, Katiba and Mk20 rifles to the storeconfig.sqf, then only the BLUFOR side has the MX rifle available, the OPFOR the Katiba and the independents the Mk20.
The same with vehicles. Does anyone know how this makes this possible?

There is a version of A3Wasteland, I do not remember if it's Armory or BIB, they added a function to do that. It only works with some things, not for vehicles, as I recall.

There they add, "WEST", "EAST" or, "GUER" at the end of each item of the store to make that restriction

In the end, there must be a file, or script, that interprets that, of course.

Search the GITHUB for these versions and trace them.

for example:

["Katiba Carbine",    "arifle_Katiba_C_F",    150, "EAST"],

for example:

["Katiba Carbine",    "arifle_Katiba_C_F",    150, "EAST"],

Por cierto, eso no funciona con el gun store
