Is it possible, and if so how, to add a text label to the product reference price on the product and category pages?

When I add a product reference price I do get a strikethrough price on my website for the specific product. However under EU regulations I have to explain what the base price is. For example is it the MSRP, a previous price or something else. With the current product reference price I'm only getting the price value with a strike through.

I'm using Odoo v18 with Theme Prime.
