Add Available field considered Customization

Hi - Just ran through the basic tutorial and am digging around so I have some very basic questions. First is…
After downloading the Sales template, I noticed fields to the left for filtering. Doing some digging I discovered how to get a popup listing “Available Fields”. If I choose additional fields listed in this box, is this considered customizing a sheet? Important since I have limited custom sheets.
Thank you for the help.


Yes, if you change the fields display on the listing page, it will be counted as customized sheets.

Any changes you make and save in the design mode will make the template sheet turn into a customized sheet. The icon marked below indicates it is a customized sheet:
