Single Select categorizing multiple items

I have a field of categories like this:

  1. Consulting & Professional Services; Venture Capital; B2B; Enterprise; Intellectual Property; Professional Services
  2. Investment Banking; Finance; Capital Markets; Venture Capital; B2B; SAAS
  3. Professional Services; Consulting & Professional Services; Venture Capital; B2B; SAAS
  4. Capital Markets; Venture Capital & Private Equity; Finance; Venture Capital; Consulting & Professional Services; B2B

I want the single (or multiple) select to parse out each individual category. Is there any way for me to do that?
