How to add statement descriptions in matrix table that repeats with scale points?

Greetings,
My matrix start with the same phrase ("I am..."), and I would like to be bolded and placed on the upper left corner when the matrix displays. Because we have a long matrix, we are repeating the scale points (i.e. repeat headers). Following the guidance from this post (https://community.qualtrics.com/XMcommunity/discussion/593/how-can-i-add-text-above-the-statements-in-a-matrix-table), I was able to come up with the code below that does the majority of what I need:
var cell=jQuery("#"+this.questionId+" td.c1:first");
cell.css("text-align","left");
cell.css("font-weight", "bold");
cell.html("My manager/supervisor…");

However, I need to repeat it whenever the headers are repeated (about every 7 statements?), and I need to make the text larger too.

Any help is greatly appreciated. Thank you in advance.

Best,
