Preds Model menu will work for what you want, You can set it up for as many models as you want. I know it is only for admins in the correct group but if you change the two times the word "false" comes up in the sp file to "true" and recompile everyone can access the model menu. Here is my models.ini i had in my menu when i used it.
I have included an models.ini EXAMPLE and the edited plugin and scripting.
These are NOT all the files you need for the plugin just the modified parts, PLEASE download Preds Model Menu plugin for all files and instructions.
