Hi there,
it will be something for 2023, but no timeline as yet has been set.
For now you can use CSS.
1. Add this CSS:
.gb-container.has-radial-background {
background: radial-gradient(circle, rgba(190,86,227,1) 0%, rgba(112,120,200,1) 50%);
}
Use this tool to create your own gradient:

2. Add the has-radial-background class to the Container Blocks > Advanced -> Additional CSS Classes field.
if you need it as a pseudo element then we can do that too. Let me know.
