Default value for checkbox field in the timeline form

Hi Team,

We have created a new checkbox field from the Timeline administration and we want to enable the default value as YES, however we don't have any settings to enable the default value like in the dropdown field.

Can we please check and see if we can add this setting. 

Business use case: We want to checkbox field with default value YES to automate the CTA creation, if any doesn't want to create CTA, they will just disable this checkbox.

Thanks,

Ravindra
