Is there a way to apply conditional formatting to specific values within a cell of comma-separated values?

  Background

1. In a Google form, I have a Checkboxes-type question with 50 options that increment by 1, from CACHE 1 to CACHE 50 .
   _{Checkbox Question( Form )}
   
    

2. In Google Sheets, each form response combines the selected options in a single column as comma-separated values.

   	A	B
   1	Timestamp	Check all that apply:
   2	9/6/2024 15:59:41	CACHE 1, CACHE 3, CACHE 17, CACHE 29
   3	9/6/2024 15:59:45	CACHE 3, CACHE 29
   4	9/6/2024 15:59:49	CACHE 1, CACHE 17, CACHE 49, CACHE 50
   5	9/6/2024 16:01:10	CACHE 29, CACHE 49

3. I want to apply conditional formatting to individual options within the comma-separated values but can't figure out how.
