How to generate a dynamic URL to a category page using a template manifest

Hello, 

I'm using a help centre template and it has custom blocks that can navigate to another page when clicked. 
 
We can put a URL in this custom block to link it to a category page called "Clients". However, we may not want it hard coded as that URL may change in the future, for example in the case it get’s deleted. I was wondering if there is a way we can call a function to generate this URL dynamically? 


Thanks in advance!
