Can you specify content conditions to be applied at a TOC level?

(I'm using the latest version of RH2020, frameless skin.)

I have my TOC separated into product sections. Some of my topics for each product are almost identical, but with a few minor differences (particularly cross references to other topics that are vastly different between the two products). What I want to do is condition the product-specific content within one topic so that I can just reuse the topic within each product section. But I don't want Product A content to appear in the output of the topic when it's in the Product B section, and vice versa. That is, I don't want the reader to have to use a dynamic filter to hide the content (because I'm not confident they'll figure that out and will just be confused). I want it hidden within the output. Is there a way to accomplish this with conditional tags?

That likely didn't make sense, so to elaborate: I want to be able to say, on output, any topic within the Product A section in my TOC should only output with Product A content, and any topic within the Product B section in the TOC should only output Product B content. This way I can reuse topics between the two.
