Yes! When creating a new size chart, select the "Build from scratch" option on the template selection screen. This allows you to:
- Define your own measurement columns and rows
- Add as many sizes as you need
- Enter custom measurement values
- Configure the chart layout and appearance to match your brand
This option is ideal if your products have unique sizing that doesn't fit any of the standard templates, or if you want to create a size chart for a product category not covered by the built-in templates.
