Gta san andreas, adding is tead of replacing vehicles.

Hello there homies, i was trying to add vehicles instead of replacing. well its process takes too much time so instead i was trying to find an easy way and then i stumbled upon a very very old app which makes the process fast but the app is too old and i am not able to understand it , its language is also different , i think its russian.

I have multiple bike mods and I want them all so yeah.

If any one tries the installer please tell how to and if you have any other faster method, kindly share

I think there is an app called ggmm which replaces the model and not add another.
