Pre-filling fields

Summary:

Hi everyone,

is there a way to prefill fields with default values?

Content (please ensure you mask any confidential information):

For example in this case, adding a cont. worker:
Is it possible to set Date of birth to 01.01.1900 and country of birth to a specific country, so it is displayed there as default instead of "Select a value"
and where to make this configuration?

Thanks and BR,

Arda
