Hello,
Unfortunately, this is currently not supported and would create problems. You can consider using the following CSS Code:
.iconlist.icon-star:before {
display: none;
}
.iconlist.icon-star li:before {
content: "\eb91";
position: absolute;
left: -1.75em;
width: 1.75em;
text-align: center;
top: 1px;
width: 14px;
}
However, this is not optimized as some the CSS Properties are applied to the .icon-* Classes causing the Font Family to not get applied properly. You can consider extending this codes further manually.
Hope this Helps!
