I managed to add a customized version to the plugin but I have doubts on two issues:
"username": "",
"ps": "Loja Virtual PadrĂ£o",
"password": "",
"run": "/",
"name": "opencart",
"title": "opencart",
"config": "",
"chmod": "",
"ext": "",
"version": "1.0",
"install": "",
"download": "{Download}/opencart.zip",
"php": "54,55,56,70,71,72,73",
"type": 1,
"md5": "fcab68cd83ddd2e411f5a41a6385cdca"
I can make the script create a subfolder with a different name for each installation I perform
