Seeking Ideas for Custom Product Personalization UI in Replo

Hey Replo community! (Note: i am not looking to hire a replo dev, just looking for any ideas)

Anyone built a good "Product Personalization/Customization" UI in Replo?
I dont really want to use a combination of Upload Kit and Inifnite Options, id rather just build it custom.

This is a recent PDP i built entirely in Replo (i think its pretty sweet) but i want to add in some customization options: https://lzrdtech.com/products/lzrd-sleeve
