Add more than a 100 variables

[Fs2121]

Hello! I am having trouble adding more than 100 variants to a customization product. I've been looking for apps to help with this, but most of them charge a fee and don't suit my needs as they require creating a new product with the app. I would like it to integrate with my existing product and add to that product's inventory. I don't want to create a new one with the app. I hope someone knows how I can do this and can help me out; I would really appreciate it. Have a great day!
