[RSS Feed/News] Adding text from node category value to forum title

[XenForo]

Is there a way to add text from the node category value into the forum title on a forum page, as illustrated below?



I understand you'd refer to .p-title-value for the forum node, using code like that below. But it's not clear how you might reference the value of the node category title and incorporate that value into the forum title.
[data-container-key="node-X"] {
.p-title-value:after {???}
}

Thank you!
