Some suggestions on GB Pro 2.0 beta global style design options

First of all, I would like to thank the GenerateBlocks team for bringing us a major update to version 2.0. Wish you:
Happy New Year!
Since the early stage of GenerateBlocks Beta, we upgraded our subscription from GeneratePress to GeneratePress One just to try out the content of GenerateBlocks Pro 2.0.
After a period of trial, we found that the design options of global styles in GenerateBlocks Pro 2.0 have some limitations. Some CSS functions are not listed in the existing options list; and no custom CSS code content is added to the existing options list. If you want to implement certain functions, you still need to insert additional manual code to achieve the desired functions.
For example:
When I want to add a dynamic ripple effect to a button, I may need the following CSS code:

.jzb-button-blue:hover::after {
animation: touchripple 1s ease-out;
}
@keyframes touchripple {
0% {
transform: scale(0,0);
opacity: .3;
}

20% {
transform: scale(25,25);
opacity: .3;
}

100% {
opacity: 0;
transform: scale(40,40);
}
}

However, the global style options cannot meet this requirement, and it does not have an option to manually enter custom CSS. In this case, I can only insert these codes into the theme custom CSS for global call; or use a third-party code management plug-in to achieve it.
Can you add an option to write custom CSS in the global style setting list to solve this problem?
Maybe my suggestion is wrong, or I haven’t found the right way to use it? I hope to get a reply and answer, thank you!
