how to make the values of a multiselect custom field into hyperlinks??

[goteamkor]

I have created a custom field of type multiselect.
I have marked a subset of my 'sites' with various field choices of this custom field.

For example, if I have 5 sites. And a custom field called 'business unit', with field choices of 'bu1', 'bu2', etc.
I have marked site1 to be part of bu1 and bu2
I have marked site2 to be part of bu1 only

I would like to make the "bu1" and "bu2" text clickable when viewing a site, so I can click 'bu1' which would link you to a custom filter for that value.
ex: https://1.1.1.1/dcim/sites/?cf_business_unit=bu1

how do I go about making the value clickable when viewing the site? is this possible?
