Is it possible to add a button that triggers a function or workflow in Zoho CRM?

Is it possible to add a button that triggers a function or workflow in Zoho CRM?

Hello, I am looking for a way to add twi buttons in the contacts section (contact list). 

First button
The first button should do a custom search (like the same you do with the custom filters in the left sidebar). But it has to be a button that searches for all records with parameter X and Y. After clicking on this "search" button I should get result based on the parameters made before. 

Second button
The 2nd button should trigger a workflow, function or should bulk update certain fields in these results.  
(I know there is a bulk edit dropdown in the contact list where I can change values with just one click, but I need a custom button).

How can I solve this? 

Thanks for help,
M.
