Jira Board JQL

Asparuh Georgiev_xs2lqa

Hello, I would like help with a JQL for a Jira Board. 
I have 7-8 custom fields, can I make a JQL filter for a Kanban Board to show only (issue type is task) tasks that contain either of the 7-8 custom fields?
 I am using Jira Cloud, Jira Software

Something like that for example: for projectX show only issues with filled (custom field1 or customfield2 or etc.) 

Thanks!

Edit: If possible I would like to avoid making new issue type specifically for the custom fields

Hi @Asparuh Georgiev ,

see if this is what you are looking for….

project = xxx and “custom-field1” is not Empty

you can repeat the bold text for each custom field
