How to change CMS filter button to be text 'contains' rather than text 'equals/is'?

Hello, I am importing CMS items for the job board page (read link below), but I need to change the filter select to base it on if the CMS field contains a certain text rather than the value is or is equal to. How can I do this?

Here is my public share link: Webflow - The Travellers Club

have you found a solution for this?
